Follow-ups from review of what landed on core-beta this evening (#519, #466, #486, #489).

  • Import screen: the type badge selectors doubled the card and table path, so the per-type colours never matched a row.
  • Run Once: the link rebuilds its href from the Heartbeat-refreshed nonce on mousedown, so a middle-click or "open in new tab" on a page left open no longer sends an expired nonce.
  • Edit page: registered without a parent, its hookname is admin_page_…; the menu now reports that name, so screen matching and the invalid-edit redirect work again.
  • Pasted code: a closing code fence is only removed when an opening one was, so an HTML snippet that ends in backticks keeps them.
  • Cache flush: both snippet tables' keys are cleared regardless of network mode, and a code_snippets/pre_flush_cache_group filter lets a cache that misreports group support fall back to per-key deletion; the fallback is now exercised through the full flush.
  • Tests: the settings layout (undefined and conditional fields, empty tabs, escaped group headings drawn once, label output, current-section fallbacks), Run Once capability with a valid nonce, the fixture save, and the hidden submenu reset between tests.

Full PHPUnit suite green locally (239 tests, 25 pre-existing skips); phpcs, eslint and stylelint clean.

Review Change Stack

Walkthrough

Changes

Admin and snippet fixes

Layer / File(s) Summary
Admin navigation and Run Once behavior
src/php/Admin/Menus/Edit_Menu.php, src/js/components/ManageMenu/SnippetsTable/TableColumns.tsx, tests/unit/Admin/Menus/...
The edit menu derives its registered hook name correctly. Run Once links refresh their nonce on mousedown. Tests cover hook registration and subscriber restrictions.
Cache group and known-key flushing
src/php/snippet-ops.php, tests/unit/Core/Versioned_Cache_Test.php
Cache group flushing supports a filter override. Known cache keys are cleared for site and network tables.
Snippet normalization and import styling
src/php/snippet-ops.php, src/css/import/_upload.scss, tests/unit/Snippets/Normalize_Snippet_Code_Test.php
Standalone closing fences remain unchanged during normalization. Import selectors target snippet column spans explicitly.
Settings layout regression coverage
tests/unit/Settings/Settings_Layout_Test.php
Tests cover hidden fields, empty tabs, escaped headings and labels, and section fallback behavior.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 73a8c

This change improves admin behavior, nonce refresh, and cache cleanup, but an upgrade can retain stale cache entries when an older cache group cannot be flushed. Several new regression tests also do not fully verify their intended behavior or isolate stored state, so the change should be corrected before merge.

Full details: Correctness And Security

Explanation

No real correctness or security defect was found. The cumulative diff changes the import selectors to match the actual row markup in src/css/import/_upload.scss:324-333 and SnippetSelectionTable.tsx:48-68. The Run Once link refreshes its nonce before pointer navigation in TableColumns.tsx:42-48. The edit hook uses WordPress's parentless hook helper in Edit_Menu.php:107-117 and 160-173. Cache fallback deletes both table key sets in snippet-ops.php:159-170. Fence removal is conditional on detecting an opening fence in snippet-ops.php:937-941. The remaining network screen-base concern predates this pull request and is not a changed failure path.

Full details: Ponytail: No Over-Engineering

Explanation

The Run Once link has two navigation paths in src/js/components/ManageMenu/SnippetsTable/TableColumns.tsx:43-49. The new onMouseDown handler refreshes href, but the existing onClick handler still prevents native navigation and calls window.location.assign() with the same URL logic. This makes normal clicks execute redundant nonce and navigation logic. The pull request activates this duplication by adding onMouseDown.

Full details: Pr Hygiene

Explanation

The title passes the conventional-commit check: it is 57 characters and starts with fix:. The PR body is present, but it includes review chronology and causal author reasoning in lines 1 and 3-7 instead of only factual change details. It also contains an explicit AI attribution block in PR body lines 13-25. Commit messages contain no AI-attribution trailers. Disclosure location: PR title and PR body, line 1.

Resolution

Remove the AI-generated attribution block from PR body lines 13-25. Rewrite the narrative and reasoning in PR body lines 1 and 3-7 as a concise factual summary of the changes and verification. Remove the disclosure at the stated location. Keep the factual test and lint results.

Full details: Scope Discipline

Resolution

Split the work into focused PRs: 1. Fix import type badge selectors in src/css/import/_upload.scss:324-332. 2. Fix Run Once nonce navigation and its tests in src/js/components/ManageMenu/SnippetsTable/TableColumns.tsx:38-50 and tests/unit/Admin/Menus/Manage/Manage_Menu_Run_Once_Test.php:104-209. 3.

Add a check for the refreshed link.

In src/js/components/ManageMenu/SnippetsTable/TableColumns.tsx Line 43, no supplied runnable check covers the new mousedown path. Add a component test for this handler. Change the nonce after render. Fire mousedown. Assert that href uses the new nonce.

As per path instructions, ask for a test when a PR adds real logic and the code has no runnable check.

Handle a failed flush for every cache group.

Line 114 applies the filter to previous-version and legacy groups. If the filter returns false, flush_versioned_cache_groups() ignores that result and falls back only for CACHE_GROUP. An upgrade can leave stale objects in an old cache group. Make flush_known_cache_keys() accept the failed group and call it for every failed flush. Add a regression test with a non-empty previous version.

Reset the run_once_ran option.

In tests/unit/Admin/Menus/Manage/Manage_Menu_Run_Once_Test.php Line 207, an earlier test can set run_once_ran to yes. The assertion then depends on test order. Delete this option in set_up() and tear_down().

Proposed fix
 public function set_up() {
 	parent::set_up();
 	wp_set_current_user( self::factory()->user->create( [ 'role' => 'administrator' ] ) );
+	delete_option( 'run_once_ran' );
 	$this->redirected_to = '';
 	add_filter( 'wp_redirect', [ $this, 'capture_redirect' ] );
 }

 public function tear_down() {
 	remove_filter( 'wp_redirect', [ $this, 'capture_redirect' ] );
 	remove_all_filters( 'code_snippets/execute_snippets' );
+	delete_option( 'run_once_ran' );
 	$_REQUEST = [];
 	parent::tear_down();
 }

As per path instructions, keep tests deterministic and reset fixtures, filters, and request state.

Test the filtered tab result.

In tests/unit/Settings/Settings_Layout_Test.php Line 82 passes if code ignores code_snippets_settings_tabs.

Add a visible tab and matching field content through the filters.

Assert that the visible tab exists in $available.

Keep the assertion that empty is absent.

As per path instructions, tests must flag an assertion that cannot fail.
