When I rightclick a message and select Create Event.. , the suggested start and end times can be in the past. This is unlikely to ever be a good default. Instead, make sure the start and end times are in the future, rounded to a whole hour. Most likely use case is that the user wants to be reminded a) the same day, when at the time of event creation it's working hours b) the next day, when at the time of event creation it's after working hours Reproducible: Always
it was fixed too. I fixed it today too.
