Zune: Tab-cycling to a hidden object results in rendering when there should not be

[Kalamatee]

Describe the bug
Tab-cycling to a hidden object (e.g. inside a Scrollgroup/Virtualgroup) results in rendering outside of the objects parent.

To Reproduce
Steps to reproduce the behavior:

1. Open a window with a scrollgroup or virtgroup object, that has cyclechain enabled children
2. Tab-cycle to a hidden item in the group
3. The active frame is drawn where the item "should be" - but it should not be drawn at all, so corrupts the contents of the window.

Expected behaviour
Nothing is drawn outside of the parent object
