Invalid display configuration window subtitle is not cleared when the issue is resolved
When there is an issue with the display configuration preventing it from being applied, and this issue is then resolved, the window subtitle warning the user is not cleared on the next attempt to apply some other new changes.
Steps to reproduce:
- Open GNOME Settings and navigate to Displays
- Do something to get to the "Changes Cannot be applied" state
- Fix the issue so that the changes can be applied
- Change some other setting
- Notice that the window subtitle still says "This could be due to hardware limitations."
