On macOS 15.5 M1:
modality=NONE, EXTENDED, header=split/custom buttos, resizable=off

Clicking on Maximize button does not maximize the Stage but places it at the lower left corner.
Same for DECORATED.

edit: pre-existing, same as master.  Not sure if this behavior is correct though.  Why full screen resizes but maximized not?  And if not resizing, why move?
