This fix is great but it looks like we need to do this across all style components across all block-components and blocks. For example, we'll need to create memos for the Style component in the Video Popup block

@mxkae @bfintal These items still has issue with stylings:

• Image block
  • Stylings doesn't show on frontend
  • When copying from WP 6.6 to WP 6.5, it causes a block error
• Separator
  • Stylings for the main separator doesn't show on frontend
