[Flipview] Flipview broken after upgraded Uno.WinUI to 5.xxx

[DosangGu]

Current behavior

When using Flipview, I expected to see only one item appers, but previous and next item also appears. In 4.xxx version, I could only find one item.

      </FlipView.Items>
    </FlipView>
  </Grid>

@ajpinedam does this look familiar?

same issue here.

Are there any temporary solutions for this issue? I need some features(like enhanced hot reload) of Uno 5.0.

[jeromelaban]

@DosangGu there isn't at this time, we'll provide updates to this issue when we will.

Still facing the issue with version 5.0.152. When do you expect the fix shipped?
