After updating to WordPress 6.4, the Button block in our theme is not applying alignment CSS classes correctly. This issue seems to stem from the removal of certain render_block filters, specifically wp_render_layout_support_flag, which are essential for proper block layout and styling in WordPress.
Expected Behavior
Button blocks should correctly apply alignment classes like wp-block-buttons-is-layout-flex.
Steps to Reproduce
Update a WordPress installation to 6.4 (without Gutenberg plugin installed)
Add a Button block.
Observe the missing alignment CSS classes.
Proposed Solution
We need to investigate the impact of the wp_render_layout_support_flag removal and explore solutions. This might include re-enabling this filter or implementing a custom solution for handling the Button block's layout and styles.
