    wayland: Fix animated cursors
    
    We must reset the image delay when stopping the timeout,
    otherwise the code setting it up thinks it is still running.
    
    This fixes cursor animation only working for the very first
    enter of a widget with an animated cursor, as seen in the
    cursors example in gtk4-demo.
