Other top bar drop-downs should be closed when another is opened
By clicking first on the inbox icon in the top bar, then the site selector down arrow, it's possible to open both at the same time. However, it's not particularly useful, as the inbox dropdown will overlap the better part of the site selector dropdown.
I propose that whenever a top bar dropdown is opened, any other top bar dropdowns that are currently opened should be closed, so that at most one top bar dropdown is open at any one time.
