Comment 1 for bug 1798847

Noting that documentation of the XUL version of this feature, which was added in 2.5, can be found here: https://docs.evergreen-ils.org/eg/docs/latest/cataloging/z39.50_search_enhancements.html

The TPAC (and Bootstrap) templates also include a vestigial (and non-functional) "Locate Z39.50 Matches" button from the list of lists in the staff user's account. Whatever else happens, those remnants should go away.
