#24649: WP_Terms_List_Table displays empty pages with large hierarchical taxonomy

 I have a hierarchical taxonomy with 1,222 terms (oy!). In the admin (wp-
 admin/edit-tags.php?taxonomy=business_areas), the first five pages of
 terms display correctly (at 20 terms per page). But the sixth page on just
 show an empty table -- no terms.

 Commenting out these lines in class-wp-terms-list-table.php prevents the
 empty display, but breaks the hierarchy:

 {{{
 if ( $term->parent != $parent && empty( $_REQUEST['s'] ) ) {
         continue;
 }
 }}}

 Then I get a list like:

 {{{
 Musical Instruments and Repairs
 — Brass Instruments and Repairs
 — Bricklaying Services
 }}}

 …which tells me the terms are getting sorted by name, irrespective of the
 hierarchy. That might ultimately be the source of the problem.
