Bug - Select inputs won't lose focus / collapse

I don’t recall this happening in previous versions, but it may of been this way for a while? In Chrome when editing a control service and navigating to Related Documents, once a dropdown has focus, it isn’t possible to click anywhere else for the select to lose focus and collapse the options. I am forced to select an option and delete to get it to close. If you leave it open and switch to a different tab within the UI (like access restrictions) then the dropdown suddenly moves to absolute position 0,0 and shows in the upper left of the ui instead of being hidden behind the tab. Very odd behavior.
