 * ParentSHistory is the ultimate source of truth for a browsing session's
 * history. It lives in the parent process and stores the complete view of
 * session history.
 * NOTE: Currently session history is in transition, meaning that we're still
 * using the legacy nsSHistory class internally. This means that currently the
 * session history state lives in the content process, rather than in this
 * class.
