Another bit of info I found for devs while trying to make a screencast of this problem.  
It seems triggered when there is more than one monitor.  
Doublescreen webcast (scroll right for 2nd screen and demo of broken dropdowns)  
[https://webm.red/EIKi](https://webm.red/EIKi)  
same actions, with one monitor disabled:

This actually seems to be some sort of bug
