workspace: Confine caption width to workspace area

When we started to only show a single caption at a time, we allowed
title captions to be wider than their corresponding window preview.
But while overlapping neighboring previews is fine, we shouldn't
allow the captions to leak outside the workspace area itself and
overlap unrelated elements like workspace switcher or dash.

This partly reverts commit b3b30f239d.
