SwipeView does not update when setting currentIndex from pressAndHold signal

Changing the currentIndex from within a button works for 'clicked' but not for 'pressAndHold'. In the latter case, the index is updated, but the visuals remain at the original page.

To reproduce:
1. Start the attached program

2. Verify that the 'click' buttons advances to 1

3. Use a 'PressAndHold' button to advance to 2

Expected behavior: the swipe view navigates to the blue rectangle 2 and the currentIndex is updated.

Observed behavior: the currentIndex property is updated, but the swipe view does not navigate to the next page.
