Unwanted notification/alert for completed scheduled task

[adn2019]

How to reproduce:

1. Schedule a task
2. when the notification/alert pops up, snooze it for 10 minutes
3. before the next notification, mark the task as complete
4. next notification pops up again, which is not needed. I had to dismiss it manually. if a task gets complete, scheduled task should not show further alerts.

Thanks for opening this up. Makes a lot of sense! Maybe we should show a confirm dialog starting "marking this task as done will also remove the reminder"? What do you think?
