@RBrid Does this issue look familiar ?

[RBrid]

@ranjeshj No - I don't think that's the same bug as the Pivot bug I am currently investigating for WinUI 3.0 Desktop.

@dpaulino, thank you for reporting this. Unfortunately we are not currently investigating WinUI2 issues that are not business or security critical (more on the policy here).

If this reproes in WinAppSDK, it would also be a lower priority issue as SelectorBar is now preferred over Pivot.
