Platform: 10452.85.0 (Official Build) stable-channel eve

Steps to reproduce the problem:
1. Create an event in google calendar for the end of the day [23.00h or so]
2. Update the event to the next day
3. The pop-up blocks ALL events around that time
4. User has to WAIT till the pop-up is gone

What is the expected behavior?
Allow the USER to configure IF the pop-up is desired or not !!!

What went wrong?
In the design, the developer did not build-in the ability that the user / customer is 'king' and wants to have the ability to configure IF the pop-up is desired or not

Did this work before? N/A
