Inline Padding Issue with Full-Width (alignfull) child Group in WordPress 6.6

[tremidkhar]

The inline padding for full-width (alignfull) groups is not being applied as expected. This behavior differs from previous versions, specifically WordPress 6.5.5, where the padding was correctly applied.

Steps to Reproduce:

Create or edit the header.html template.
Add a full-width (alignfull) group with inline padding.
Save the changes and view the header on the frontend.

Expected Behavior:

In WordPress 6.5.5, the header displays with the root inline-padding for spacing.

Observed Behavior:

In WordPress 6.6, the inline padding is not applied, and the header appears without any spacing.

Environment:

WordPress Version: 6.6
Theme: Twenty Twenty Four (with changes only to the header.html template)

Below is a sample code snippet for the header.html template used for testing:

<!-- wp:group {"align":"wide","style":{"spacing":{"padding":{"top":"var:preset|spacing|30","bottom":"var:preset|spacing|30"}}},"layout":{"type":"constrained"}} -->
<div class="wp-block-group alignwide" style="padding-top:var(--wp--preset--spacing--30);padding-bottom:var(--wp--preset--spacing--30)"><!-- wp:group {"align":"full","layout":{"type":"default"}} -->
<div class="wp-block-group alignfull"><!-- wp:group {"layout":{"type":"flex","flexWrap":"wrap","justifyContent":"space-between"}} -->
<div class="wp-block-group"><!-- wp:group {"style":{"spacing":{"blockGap":"var:preset|spacing|20"},"layout":{"selfStretch":"fit","flexSize":null}},"layout":{"type":"flex"}} -->
<div class="wp-block-group"><!-- wp:site-logo {"width":60,"shouldSyncIcon":true} /-->

<!-- wp:group {"style":{"spacing":{"blockGap":"0px"}}} -->
<div class="wp-block-group"><!-- wp:site-title {"level":0} /--></div>
<!-- /wp:group --></div>
<!-- /wp:group -->

<!-- wp:group {"layout":{"type":"flex","flexWrap":"wrap","justifyContent":"left"}} -->
<div class="wp-block-group"><!-- wp:navigation {"ref":5,"style":{"spacing":{"margin":{"top":"0"},"blockGap":"var:preset|spacing|20"},"layout":{"selfStretch":"fit","flexSize":null}},"layout":{"type":"flex","justifyContent":"right","orientation":"horizontal"}} /--></div>
<!-- /wp:group --></div>
<!-- /wp:group --></div>
<!-- /wp:group --></div>
<!-- /wp:group -->

Here is an updated header.html template code.

<!-- wp:group {"style":{"spacing":{"padding":{"top":"var:preset|spacing|30","bottom":"var:preset|spacing|30"}}},"layout":{"type":"constrained"}} -->
<div class="wp-block-group" style="padding-top:var(--wp--preset--spacing--30);padding-bottom:var(--wp--preset--spacing--30)"><!-- wp:group {"align":"full","layout":{"type":"default"}} -->
<div class="wp-block-group alignfull"><!-- wp:group {"layout":{"type":"flex","flexWrap":"wrap","justifyContent":"space-between"}} -->
<div class="wp-block-group"><!-- wp:group {"style":{"spacing":{"blockGap":"var:preset|spacing|20"},"layout":{"selfStretch":"fit","flexSize":null}},"layout":{"type":"flex"}} -->
<div class="wp-block-group"><!-- wp:site-logo {"width":60,"shouldSyncIcon":true} /-->

<!-- wp:group {"style":{"spacing":{"blockGap":"0px"}}} -->
<div class="wp-block-group"><!-- wp:site-title {"level":0} /--></div>
<!-- /wp:group --></div>
<!-- /wp:group -->

<!-- wp:group {"layout":{"type":"flex","flexWrap":"wrap","justifyContent":"left"}} -->
<div class="wp-block-group"><!-- wp:navigation {"ref":5,"style":{"spacing":{"margin":{"top":"0"},"blockGap":"var:preset|spacing|20"},"layout":{"selfStretch":"fit","flexSize":null}},"layout":{"type":"flex","justifyContent":"right","orientation":"horizontal"}} /--></div>
