I got a different result with your testcase attached to the bug ("focus event" is always fired and follows the "active element"). Could you confirm or not, please.

Recently tested on Windows 7, Ubuntu and OSX.

Open the attachment in one window. The element is set active and the focus event is triggered. 

Open another window and keep it side by side with the one containing the attachmend. As long as the new window is active, the focus event is not triggered, but the activeElement is updated. 

Set focus on the window with the attachment and the focus event starts triggering again.

I believe this is purposeful: focus is global, so things that are focused in non-active windows don't actually get focus until that window itself gets focus.  Neil?
