         The mime data from Wayland clipboard is not the exact same image, so two
         image items are listed (first time restarting plasmashell). But after
         images are saved to local, they have the same uuid again. So klipper
         starts to become confused after the second time restarting plasmashell.
 
         This is caused by QPixmap::from(QImage).toImage() erasing metadata in the
         image, and Wayland clipboard is async, so another identical image is added
         to clipboard.
 
         This test tries to reproduce the process to trigger the original bug by
 
         1. Enable image history
         2. Copy faulty image data
         3. Reload Klipper
