Blazor Hybrid Windows: Window was already activated when minimize and restore from taskbar

[samhouts]

Description

I have a Blazor Hybrid app, debugging in Windows. I'm running against maui main.

If I minimize the app and then try to restore it again by clicking on the icon in the taskbar, I get an instacrash:

System.InvalidOperationException

@samhouts is this only happening with the Blazor hybrid template? Or are you running into this issue with any of the other templates?

@samhouts this is an issue with WinAppSDK (can't find the original issue)

WinUI calls Activated twice when you maximize, and we aren't debouncing that second call.

I forgot about this when I added this exception :-)
