What conditions are these? I would expect to see this described in the
test plan to ensure the fix is properly tested. Can this be made more
clear, please?

Bug description:
[ Impact ]
When dragging a window around, GNOME Shell might crash and log out the
user.
To trigger the bug, some conditions need to hold so that GNOME Shell
denies the drag action; after that it will crash trying to handle the
failure to drag. It is unclear how to trigger these conditions
naturally.
[ Test Plan ]
1. Log-in to Ubuntu on Xorg
2. Open an application window
3. Drag the window around by its title bar
4. Verify that GNOME Shell didn't crash and log you out
[ Where problems could occur ]
The patch affects the ending of a drag operation.
A problem may manifest with GNOME Shell crashing, or becoming unresponsive to
inputs after ending a window drag.
[ Other info ]
Ubuntu version (24.04)
