Masonry items jump between columns upon size change

Current behavior

In a Masonry layout with optimizedItemArangement enabled, items sometimes jump to other column when their height is modified. This results in bad UX.

See video below:

Expected behavior

There should at least be a prop that disallow items to switch columns upon size change or it should be enabled by default, at least for the visible items.
Unexpectedly switching columns seems glitchy and leads to bad UX.

Reproduction

Reproducible in flash-list fixture app:

1. Open ComplexMasonry screen example
2. Click on Item 9 or Item 13 to increase their size and notice how other cards jump to different column

Platform

• iOS
• Android

Environment

FlashList version: 2.2.2

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 with the fixture app's ComplexMasonry screen and reproduce the issue by increasing the size of Item 9 or Item 13 on both listed platforms. Compare the column assignments before and after the size change; the work is done when visible items no longer jump columns unexpectedly or the requested column-stability behavior is available.
