[BUG]: Window class "WinUIDesktopWin32WindowClass" freezes on first launch

Summary
I noticed buggy behavior in two separate applications - Windows Photos (not the legacy one) and Proton VPN. Their main windows have the same class name WinUIDesktopWin32WindowClass.
When I first open either of them, the main window opens up and gets tiled by komorebi. After that, the window doesn't respond to user input, including mouse hovers and clicks, moving and resizing, etc.
To get around this, I can do either:
- Switch focus to a different window, then
komorebic focusback into the faulty window. - Alt+Tab and select the faulty window. After that, the window gains focus and user input is processed normally again.
Adding them to the ignore_rules list also prevents the issue.
