Calendar pop-up can't be cleared easily
The calendar popup isn't cleared by the standard of pressing [Esc].
- Click on a task to edit it.
- Click on its date. A calendar pops up.
- Press the [Esc] key.
Result: the task editing closes but the calendar pop-up remains.
Desired result: the calendar pop-up is closed (optionally the task editing could stay open, but at least the calendar pop-up should go away).
Doing something like clicking on another task will close it but it's really annoying when I realized I didn't want to change the recurrence after all, etc.
