Sticky header container blocks touch events on content beneath it

Description

We are using a two column layout to display events with sticky day headers. Because of this unique arrangement, the stickyheader is blocking interaction from any elements beneath it.

When using stickyHeaderIndices with numColumns > 1, the sticky header's CompatAnimatedView container (position: absolute, left: 0, right: 0, zIndex: 2 in StickyHeaders.tsx) spans the full width of the list and intercepts all touch events on the content directly below it.

In our case this means the first item rendered next to a sticky header cannot be pressed.
Theoretically the fix is a one-line change: adding pointerEvents="box-none" to the CompatAnimatedView in StickyHeaders.tsx, which makes the container itself transparent to touches while keeping its children (the header content) interactive.

Current behavior

I've produced a working example:

Expected behavior

When pressing on a header, the input event is not blocked and is passed through.

Checklist

• I've searched existing issues and couldn't find a duplicate
• I've provided a minimal reproduction (Expo Snack preferred)
• I'm using the latest version of @shopify/flash-list
• I've included all required information above

Start by opening StickyHeaders.tsx and reproducing the issue with the linked Expo Snack using stickyHeaderIndices and numColumns greater than one. Check the CompatAnimatedView touch behavior and verify that the first item beneath the sticky header can be pressed while header interactions remain functional.
