Cancel edit prompt won't go away

When clicking off the message box while editing a prompt, the pop up “Cancel Edit?” appears. Sometimes, this happens when I didn’t mean to cancel the edit, so I click “No, keep editing”. Occasionally, me clicking that prompt away triggers the prompt to appear again, for whatever reason. I have tried clicking on the background within the bounds of the message box. My only choice when this happens is just accept I’ll have to retype the edit, because wether I click “Yes” or refresh, the prompt is reverted to before I started editing.
