[WP 6.6] Card block - When saving Faded layout as a synced pattern, it freezes the editor

[andeng1106]

Describe the bug

• Issue inconsistently happens for other Card block layouts
• Usually happens for Faded layout
• Issue only happens if I save it as a synced pattern
• Note: Lagging/freezing also happens for other Stackable blocks but inconsistent. Please kindly check also if a fix for the Card block might fix the lagging also.

@Arukuen @bfintal Both this issue and #3229 still occurs on WP 6.6 RC3. Changing status again to "In Progress".
