Regression possibly introduced with #3543

STR:

1. Simple Editor is disabled
2. There's at least one event on daily view
3. User clicks on an empty time slot
4. User does not fill anything in the revealed sidebar (event is empty)
5. User clicks on other pre-existing event;
6. Sidebar for other pre-existing event reveals;
7. Empty event that user just jumped focus from gets saved as empty
8. User observes title "Untitled event"

Looks like a bug to me as after heavy daily planning sessions you get to clean up bunch of those empty events.
Do you think it was caused by this PR?
Perhaps there's another issue where this bug is being tracked?
