Seems fine, tested here didn't saw nothing bad. but @drasticactions maybe is a better one to give the 2nd thumbs up.

Adding a test would be great.

[MartyIX]

A test would require resizing a window. I'm not sure how stable that would be (MacCatalyst supports setting max/min width&height, not with & height; there is a workaround but still).

But I think I can try. Ideas for approaching the test are welcome.

@mattleibow can't we set the window size via API? I wonder if we can write a UITEst that uses that api and then checks if the adorner changed position

I have just realized this PR might depend on #21357 to add a proper test.
