Bug 432455

SUMMARY
canvas input settings shortcuts stop responding from time to time, most common situation that can reproduce the bug all the time is when saving the file after a new file creation.
A temporary fix is to open the settings dialog and just close it. The behavior gets back to normal.

Tested on Android11/Samsung galaxy TabS7+

While painting sometimes the shortcuts from canvas input settings stop responding , usually on some operations that draw another window on top of krita's but can not reproduce it 100%.  

STEPS TO REPRODUCE
1. open krita
2. create new document
3. pan , zoom , rotate or do any operations involving shortcuts set in Canvas Input Settings(default space + left button and drag to pan canvas) all works as intended
4. save the document
5. try to repeat step 3. nothing works, i can pan, zoom rotate with the fingers or using the hand tool but the spacebar+ left click does not work, nor any other shortcut set in canvas input settings
6. open settings>configure krita dialog
7. close the dialog
8. repeat step 3 , all works as intended 


OBSERVED RESULT
sometimes the shortcuts set in canvas input settings stop working after some operations (100% reproductibility for me are the steps described above but from time to time on longer drawing sessions they stop working). Opening the configure krita dialog and just closing it will do the trick all the time.

EXPECTED RESULT
shortcuts set in canvas input settings should work as intended
