// The joint session history of a top-level browsing context is the union of
// all the session histories of all browsing contexts of all the fully active
// Document objects that share that top-level browsing context, with all the
// entries that are current entries in their respective session histories
// removed except for the current entry of the joint session history.
// Just a stubbed implementation is currently required. However, more support
// may be needed in the future for other clients.
