1. Run the gallery_controls2 example.
   It's in Examples\Qt-6.0.0\quickcontrols2\gallery\CMakeLists.txt of an installation.
2. Click the hamburger menu in the upper left corner.
3. Click "Delegates".
4. Swipe a SwipeDelegate to the right.
   Its caption changes to "Remove".
5. Click on this SwipeDelegate.
   Nothing happens.

It should be removed from the view instead. This used to work fine in Qt 5.15.
