1581 fix long dd element styling

Updates previous commit of 1581-lnxstr merge which caused long, multi-line dd elements to go the full width of the panel. This fixes that while not causing the problem that prompted this ticket. It’s still not perfect; If a dt wraps to two lines and its dd is only one line, dt/dd pairs below go out of sync. The only way to reliably fix all dl issues is to wrap each dt/dd pair in the whole code base in a div.
