Title: Add class 'vertical-scroll' to the working set container when the scrollbar is present

Provides a hook to adjust the layout of a working set item when the
scroll bar pops in, which is useful if you are laying something out to
the right edge of that view.

I ran into the need for this in creating a related files extension.
