📝 Walkthrough

Walkthrough

A CSS hover style rule was removed from the RepeatingGroup table module. The change eliminates an explicit background-color: unset declaration on hover for table body rows, allowing hover states to default to inherited or browser-default styling instead of being explicitly reset.
