Problem: 

When I want to select an option low down in a long secondary menu, I must first move my curser from the primary to the secondary and then move down to my desired option. This is frustrating. 

Steps to reproduce:

In Hiring Demo process, add group by variable and try to directly select the bottom option. 

(see attached video) 

Actual result : 

Menu disappears, unless I carefully navigate from one menu to the other.

Expected result: 

There is a slight delay on the hiding of the menu. 
Similar to what Omran did for the Outlier analysis page tooltip.
