macOS Tahoe's Apple Music app has this annoying bug that whenever I launch it, it opens up in this small size. It doesn't remember its last position/size. I say it happens about 50% of the time and it happens on all my 3 macOS Tahoe machines.
I'm not sure how you mess up the window's `frameAutosaveName` but here we are. No other app seems to have this issue.
@marioguzman Passwords does this and defaults to an irritatingly small window size if you use the red traffic light to close the window. You have to quit the app without ever closing the window to retain its size/position.
Maybe this got fixed in Tahoe (I doubt it), but it affects Sequoia and the Tahoe betas.
I think I’ve seen the same behaviour in other “new generation” macOS apps.
