<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Editor: Invalidate blocks metadata cache when needed in `WP_Theme_JSON::get_blocks_metadata()`.
This change ensures that user-supplied global styles settings for blocks aren't lost due to sanitization. This could previously occur due to outdated blocks metadata that did not include all registered blocks.
