Description Tobias Fella 2026-03-03 16:22:09 UTC 
SUMMARY
Removing last widget from grouping widget leaves behind the header as if the content widget was still there

STEPS TO REPRODUCE
1. Add Grouping widget
2. add any content widget
3. remove content widget

OBSERVED RESULT
Header line is still there; it disappears after the content widget was actually deleted (i.e., after the notification timeout); the widget still does not entirely go back to its empty state, though.

EXPECTED RESULT
Grouping widget goes to the empty state entirely and immediately
