Various minor fixes to "apply the history step"

* Remove the unused  fireNavigateEventOnCommit argument. Closes #9800.

* Fix "apply the reload history step"'s declaration to match its call site.

* Add the missing anchor for descendant navigable traversal navigate events.

* Make the linking text clearer for a note that referenced a specific part of the "apply the history step" algorithm.
