Can't clear Background color

Steps:

Create a WinFx Window

In the properties window of VS, set Grid Background to gray.

Value is converted to #rgb value

Attempt to remove the value just added.

Results:

A message box pops up saying "Property Value is not valid"

Details area says empty string not allowed.

Hit ok, the properties window has focus and the Background value has been restored.

Expect :

To be able to set the Window properties back to the original state.

I expect this is true for other properties.
