SUMMARY
unexpected exit of screen mode when enter canvas-only mode in full screen when title bar is set to be hidden in related preference

STEPS TO REPRODUCE
1. open krita
2. open any picture(or create a new one)
3. open Preference, make sure "canvas-only settings"-"Titlebar" is ticked
4. enter full screen mode via buttons in upper left corner of the window ( the green round button provided by macOS )
5. enter canvas-only mode via shortcut or menu, then do it again to exit canvas-only mode

OBSERVED RESULT
krita exit canvas-only mode and exit full screen ( that is to say, it back to a window )

EXPECTED RESULT
krita will exit canvas-only mode but stay at full screen when entered canvas-only mode in full screen

SOFTWARE/OS VERSIONS
macOS: 15.3.2 (24D81)

ADDITIONAL INFORMATION
when disable Titlebar in Preference, the program will stay at full screen when exit a canvas-only mode which is entered from full screen mode. This is the behavior I hope it can have
