Maximizing makes the app go fullscreen

[Zopenzop]

I am using a custom button widget and appWindow.maximizeOrRestore() to maximize / restore the window. I have noticed that when my taskbar is set to automatically hide and I maximize my window like given above, the taskbar can't be triggered and it won't show up after taking my mouse pointer all the way to the bottom of the screen, while I can trigger the taskbar even after maximizing other apps like Chrome, VSCode, etc.

I am on Windows 11 Build 22000.
