// Unlike the attributes in FrameOwnerProperties, these attributes are never
// updated after the framed document has been loaded, so two versions of this
// structure are kept in the frame tree for each frame -- the effective policy
// and the pending policy, which will take effect when the frame is next
// navigated.
