If a user has the preference "Prompt me when entering a blank edit summary" selected, VisualEditor's save dialog has to be closed and reopened to work. The "Save" button is greyed out even when an edit summary is entered.

To reproduce:

1. Enable Preferences>Editing>tick Prompt me when entering a blank edit summary
2. Attempt to save a VE edit and the prompt for an edit summary comes up, with save not an option
3. Enter an edit summary
4. Save is still not an option
5. Exit out of the dialog by clicking X and click save again
6. You can now save your edit with an edit summary
