Fix oversized titles in the overview (alternative solution)

Another solution to fix the issue with the oversized titles in the overview. Instead of avoiding setting the width of the label (done in !207 (merged)), just reintroduce the solution that was already in place before the new overlay design was implemented.

I'm in favor of this solution since we'll need to do it this way anyway as soon as we want to manipulate the length of the overview labels ourselves, which we do in !214 (merged).
