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

[iarp]

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

Additional notes:

• It only happens for the floating editor
  • After saving the from the full size editor this doesn't happen because after saving it closes and does not show the floating read-only preview again.
• It only happens for "Update this and all future" and not "Update this occurrence"
