3. Save as draft or publish the post.
4. Reload the post editor page & try to replace feature image, then you will notice that the description field is empty.

Hello @jogashst,
I tried to reproduce your issue with saving the post as a draft and publishing, but it seems to work perfectly. In latest clean setup with Twenty Twenty-Five and no plugins were installed.

### Description

​https://github.com/WordPress/wordpress-develop/blob/7d10dd7b0fde2a782395887c2d66439481440f9b/src/js/media/views/attachment.js#L587-L589

This code bails out early when the updated value matches the DOM, but the model starts with defaults (e.g., an empty title), and AJAX delays can leave values uninitialized. This can block re-renders, especially when the data becomes available post the AJAX call.

While the early return prevents unnecessary updates, it shouldn't apply when multiple changes occur simultaneously during initialization. Instead, bailing out only when a single change occurs—and it matches the DOM—ensures proper hydration and fixes the bug.
