[Gallery][Windows][ShadowContainer] Crash on selection of Tabbar Neumorphic Style dropdown toolkit sample page.

Current behavior

Crash on the selection of Tabbar Neumorphic Style dropdown toolkit sample page in Gallery for Windows. This same crash happened in an Uno app developed by me for my organization. It is working fine in Other Heads i.e. [Wasm], [Desktop], & [Andi]

Msg:
System.Runtime.InteropServices.COMException

Anything else we need to know?

fyi @MartinZikmund & @kazo0
Maybe @morning4coffe-dev can help take a look

@eriklimakc, @vatsashah45 does this happen with your test with the new single project structure?

[morning4coffe-dev]

@agneszitte Jup, I can investigate more

[morning4coffe-dev]

I was able to repro on a newly created app with the latest packages. After a bit of investigation the issue is in the NeumorphicBaseContentTabBarItemStyle specifically in the BADGE section here:

Uno.Gallery/Uno.Gallery/Uno.Gallery.Shared/Views/Styles/NeumorphicStyles.xaml

Line 2396 in 478b137

<!-- This part can be replaced when InfoBadge will be available in WinUI3 -->

The Visibility of the Ellipse and Border causes an exception on Windows. Before trying to fix, my question @agneszitte can we already replace it with InfoBadge from WinUI or are we still blocked?

FYI @MartinZikmund, @kazo0

[MartinZikmund]

As InfoBadge is now available everywhere, I think it would make sense to replace the Uno-specific code with InfoBadge directly
