Posts / Comments tab, Post list subtab. Viewing source to get back to where the perms for the "Publish Now" feature is controlled, I noticed

<td class="tskst_$post_pst_ID$">

It comes from one of two files: /inc/items/views/_item_list_table.view.php or {{same folder}}_item_list_track.view.php but beyond that I know nothing. Doesn't seem to affect anything so it's kinda low on the totem pole of fixability eh?
