This PR fixes breakpoint icon alignment to also be at the end of a
rendered entry and enables editing breakpoint qualities when there's no
active session.

The alignment issue was caused by some icons being invisible, so the
layout phase always accounted for the space they would take up. Only
laying out the icons when they are visible fixed the issue.
