fix(input-group): ignore portaled descendant events

[songkeys]

Summary

• Ignore mouse events from portaled descendants before applying the InputGroupAddon focus behavior.
• Preserve focus behavior for physical non-interactive addon content and interactive descendants.
• Add regression coverage for physical, interactive, and portaled event targets.

Why

React events from portals bubble through the React component tree even when the event target is not physically contained by the ancestor DOM element. Non-interactive content in a portaled Popover, Select, or Menu can therefore reach InputGroupAddon, call preventDefault, and focus the grouped input.

Checking physical containment before the existing interactive-element check keeps the focus convenience scoped to the addon DOM subtree.

React documents the portal event behavior here: https://react.dev/reference/react-dom/createPortal#caveats
