Description
Two issues reported this, but I wasn't able to reproduce it for the moment.
https://wordpress.org/support/topic/advanced-columns-block-drops-wrapper-html-on-block-validation-recovery/
From what I understand, they say it's a regression from this change #2777
Step-by-step reproduction instructions
Steps to reproduce
Build a page with an advanced-columns block, give it a background color and full-width alignment
Open the page in the block editor — if a block validation error appears, allow recovery (or simply save without addressing it)
Save the page
View the page on the front end — the wrapper
is gone, background color and layout are lost
Why this is serious
The page appears completely unstyled with no visible error anywhere — not in the editor, not in the PHP error log. The user has no indication anything went wrong until they view the front end. On a Neve Pro site where advanced-columns is used on high-traffic pages this is a silent, recurring breakage triggered by any ordinary edit.
Suggested fix
Register a PHP render_callback for themeisle-blocks/advanced-columns so the block renders server-side. This would make the block resilient to any serialization mismatch and is the correct pattern for blocks whose front-end output depends on server-side state. Alternatively, ensure the JavaScript save() function reliably outputs the wrapper HTML in all recovery scenarios.
