Hey, If you have an element which you have used within VisualStates, such as in a Button, when you delete that element - it doesn't seem to remove it from those VisualStates, instead it shows as something else (in my case as the ControlTemplate itself)

1. Create something with visual states, such as a ControlTemplate Button.
2. Add an element, such as a Rectangle Shape.
3. In one of the the VisualStates, modify a property of the element, such as Colour
4. Delete the element from the Navigatior.
5. Observer when you view the VisualState that used the deleted element, there is a lingering entry & it shows as the ControlTemplate parent, which is confusing as that cannot have properties set on it.

I would expect it to:
1) Remove all instances of the delete element
or
2) Display some kind of "<Deleted Element>" type message.

I've attached a before (left) and after (after) image.

Cheers
