REGRESSION(285421@main): Crash when restoring session state while a
provisional history item is set
https://bugs.webkit.org/show_bug.cgi?id=283924
rdar://140463108
Reviewed by Wenson Hsieh.
When session state is restored, the current history item index is updated, but
the provisional index is
not cleared. So, if a provisional index was set before the session was
restored, it will be stale and
point to an index that is incorrect or out-of-bounds `m_entries`.
