Maximizing Windows while Stage Manager active. Frame close to the stages at the left, but window is fully maximized?!

Hi,

I just started to use Stage Manager and quite like it.

One issue I have with Multitouch is, that when I want to maximize some windows, in it's preview the frame outline looks nice and is close to the 'stages' on the left side of the screen, but when the window is maximized it goes over the full screen. Is there any setting I can change, or is it just a bug? As the preview frame-outline does show it correct there should be some option to change it, or am wrong?
