Bug summary

On qt(6)cairo, qt5agg or qt5cairo (or mplcairo.qt6), after the mouse cursor is changed (by activating zoom or pan mode and moving the mouse over an axes), deactivating the tool fails to change back the cursor to pointer/arrow. (Switching the active mode between zoom and pan does change the cursor, though.)

Curiously enough, this doesn't occur with qt(6)agg.

Code for reproduction

frompylabimport*;gca()# then activate a tool, move the mouse, deactivate a move, as described above, and move again the mouse.

Actual outcome

Cursor fails to go back to arrow/pointer.

Expected outcome

Cursor goes back to arrow/pointer.

Additional information

This is on a conda python but with pip installed packages.
This appears to affect matplotlib at least as far back as 3.4.0 (didn't check further), soperhaps this is rather a problem with some recent versions of qt?
The fact that I observe this with qtcairo/mplcairo.qt but not with qtagg is rather strange, though, as both inherit the same cursor handling code from the base class.
