[v6][Bug] Repeatable UI is broken

[tabacitu]

Reported by Pedro: repeatable buttons are completely broken in Theme-Tabler

Note that we should NOT do fixes that are tabler-specific in CRUD. But we can can either:

• (a) change CRUD in a way that is general and ok for all themes
• (b) add CSS in theme-tabler to make repeatable look good there too
