[Bug] CarouselView.CurrentItem not working at all

[viktorszekeress]

Description

I have a CarouselView with ItemsSource and CurrentItem bound to dependency properties defined in the page. Then I have 2 buttons to increment and decrement current item. The problem is that setting CarouselView.CurrentItem has no effect on 5.0-pre5. Although it does work properly on version 4.8.

Interesting part is that after swiping the item, current item 'auto-corrects' and starts to work properly.

Steps to Reproduce

1. Open and run the attached solution
2. Click Next button
3. See that CurrentItem item defined in the page is changed, but CarouselView doesn't navigate to the item

Expected Behavior

CarouselView should navigate to CurrentItem.

Actual Behavior

CarouselView stays at initial item.

Basic Information

• Version with issue: 5.0-pre5
• Last known good version: 4.8
• Platform Target Frameworks:
  • iOS: not tested
  • Android: 10.0
  • UWP: not tested

Screenshots

This seems to still be an issue on iOS.

This still does not work on Android. If i set current item to 3 - it will not update the carousel position, but if i set it to 1 or 2 it works fine.
In other words, it will update if CurrentItem is only two places from current position
