Description

SwipeItemView and SwipeItem background doesn’t update on AppTheme change (Light/Dark).

[.Net10]

net10.mp4

[.Net9]

net9.mp4

Steps to Reproduce

1. Open the SwipeViewDemos project.
2. Navigate to SwipeViewEventsPage.
3. Add a new SwipeItemView or SwipeItem with an AppThemeBinding for its background color. For example:
   <SwipeItemView BackgroundColor="{AppThemeBinding Dark={StaticResource Primary}, Light={StaticResource Yellow100Accent}}" />
4. Run the app.
5. In the list, open the “SwipeView events” item to navigate into the page.
6. Reveal the swipe actions (swipe left/right to show the SwipeItemView).
7. Toggle the app/OS theme between Light and Dark while the page is visible.
8. Observe the SwipeItemView background:
   • Expected: it updates to the correct theme color after the theme change.
   • Actual: it remains with the initial color until the page is recreated or the background is reassigned programmatically.
