Closing the Reset sheet while the reset request was in flight left the form editable, so a prompt edit made then was replaced by the reset response and the leave guard could report the form as saved. The form's fieldset is now disabled while a prompt reset is pending as well as during a save, so no edit can be made that the reset response would overwrite.
