The problem here seems to be that passing 0 will cause deletion of the
property. That means that since it's missing from the window, it is
inherited from the parent window. You would need to keep the SUPPORT
property but set the value to 0, to explicitly tell that portrait is not
supported and should not be inherited from the parent.
