Edit existing repeating event, Update this and all future: closing popup requests confirm to discard changes

Steps to reproduce

1. Create a repeating event of any kind
2. Edit the newly made event and click "Update this and all future"
3. Attempt to close the information dialog/modal which displays the event information

Expected behavior

Closing the dialog/modal should make it disappear without further interaction necessary

Actual behavior

Another dialog appears requesting to Discard Changes? Clicking Discard changes or Cancel does not actually change anything or undo anything on the event. I would not expect it to do so because the changes were already made and saved on the edit dialog/modal

Start by reproducing the repeating-event flow in the Calendar app with Firefox: edit an event, choose "Update this and all future," then close the information dialog. Trace the modal close and discard-confirmation behavior. Done means the saved event information dialog closes directly without an unnecessary discard prompt or changes to the event.
