Swipe to delete (SwipeDelegate) does not work on mobile devices

Tested with Qt 5.15.2 (commercial) and following devices:

• Samsung Galaxy S10 with Android 10.0
• Samsung Galaxy Tab S2 with Android 7.0
• iPhone8 with iOS 14.4
• Android emulator 8.0
• iOS simulator 13.7

Steps to reproduce:

1. Run "Qt Quick Controls - Swipe to Remove" project from Examples or attached sample app (https://doc.qt.io/qt-5/qml-qtquick-controls2-swipedelegate.html) 

2. Swipe on the cell to delete it. 

3. Tap the 'Delete' button

Expected: Cell is removed from the list.

Actual: 

• The cell is not removed. The delete button changes its color, but nothing more happens.
• See attached videos from mobile and from the desktop for comparison:  swipe-to-delete-mobile.mp4 swipe-to-delete-desktop.mov
• It works even worse with Qt 6.0.0: Swipe action does not work on mobile (Delete button does not appear at all), on desktop pressing Delete does not remove the cell. 

NOTES: It works well on Desktop (MacOS)
