Workaround for issue #571

<Visible> condition taken from Confluence skin.

All changes have been tested.

There are however possibly still some conditions where the bug occurs, which I've been unable to test.
Possibly:
-MusicvideoLatestItems2
-LatestPicturesItems2(+home)

The bug also occurs in custom_1115_Featured.xml (the Featured Overlay on the main menu), where I was not able to solve it without the solution looking like crap.
