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

See original GitHub issue

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:
