Mouseover to show "See also" titles

I use the 3 pane view. When I am classifying articles, the two additional panes appear at the right: suggested groups for the highlighted article, and below that the “See also” pane.

Titles in the “See also” pane are truncated. It would be lovely to be able to mouse over each and see the full title.

Which is what happens, over here. It takes a short while, hovering the cursor over a title, for it to appear. Document title with path.
