User blog comment:Kirkburn/Technical Update: April 2, 2013/@comment-1474707-20130402213412

So weeks and weeks ago one of these updates screwed up linksuggest when editing, and it's mostly back to how it was except it's still disappearing off the bottom of the screen, it makes adding categories to pages (in the normal way) really hard.

Annoyance over this is compounded by the fact that you (Kirkburn) promised that with the new editor source mode editors would get space at the bottom of the editing window (to avoid this kind of thing) then went back on that promise.

At what level of priority is the bug of linksuggest disappearing off the bottom of the edit window (reported weeks ago)?
