Comment (by isabel_brison):

 > This is the reason why 48894.3.diff​ was reusing the existing keydown
 event for the "My account" item. I think it's best to attach just one
 event and use the previous approach for all items.

 @afercia by previous approach, do you mean handling both Space and Enter
 with `keydown`? An alternative would be to detect Space in the `keydown`
 handler and prevent default for it there. It's a bit messy though.

 I'm checking the "View Admin As" dropdown on trunk and it's not keyboard
 accessible. I can open it on hover, but can't even get focus to the top-
 level item to open with Enter. Not sure why though: it's using `div`s
 instead of links but they have `tabindex="0"` set.
 The event handlers I added should work for any `li.menupop > .ab-item`,
 but the element has to be focusable to register the keyboard event.
