Reproduces: always

Expected behaviour:
When an already detached view is hidden by another (non-eclipse) window / application, focusing on the main eclipse window also brings the detached view into foreground.

Actual behaviour:
After every start of eclipse this does not work properly. The hidden detached views are not getting to foreground when (re-)focusing the main window (the window / application hiding the detached view does not matter, can be anything).

Workaround: 
Make eclipse somehow recreate the detached view. After that is done, we are back to the expected behaviour. 

Some ways to make eclipse recreate the detached views: 
* Re-attach and detach the view again
* Detach the view into an empty space (I guess that duplicates the whole view and deletes the old one, but the new view behaves properly)
* Switch perspective in main eclipse (can be done twice so you end up in the original perspective, but with working view behaviours)
