…n options getJSXElementActionPaths collected handler attributes with path.traverse, which also visits nested elements, so a tracked component inside another tracked component was wrapped with the outer element's ddValues (useContent/getContent) and then skipped on its own visit. Only accept handler attributes that belong to the element being processed. Fixes DataDog#1469

What does this PR do?
Fixes #1469.
In
getJSXElementActionPaths, handler attributes are collected withpath.traverse({ JSXAttribute }), which also visits nested elements. When a tracked component contains another tracked component, the inner component's handler was collected during the outer element's pass and wrapped with the outer element'sddValues(options.useContent,getContent); the inner element's ownJSXElementvisit then skipped it as__wrappedForRum.This PR only accepts handler attributes whose parent is the element being processed (
subpath.parentPath?.node === path.node.openingElement). Nested tracked elements are then wrapped on their own visit with their own options and content. Descendant collection ofdd-action-name/accessibilityLabelliterals (compound components) is unchanged.Two tests cover a tracked container with and without its own handler enclosing a tracked button; the existing suite (210 tests) passes.
Motivation
We track layout containers (Tamagui
XStack/YStack) withuseContent: falsefor their ownonPress, and every tracked button nested in one lost its content getter and reported as the bare component name. With auseContent: trueouter component the inner button instead reports the outer component's content.Additional Notes
The fix is a single condition; before/after output is in the issue.
