Bug 10704: make OPAC highlighting work across previous/next travel

To test

Enable 'OpacHighlightedWords'

1) Run a search with multiple results
2) Click on a title of one of the results to get the full record
display. Hit highlighting SHOULD work on this page.
3) Use either the "Next" or "Previous" buttons on this page
(opac-detail) to move to the next or previous record.
4) Moving forward or back, the highlighting should still be working on
the page.
