Improve label and text wrapping (#14113)

* Improve label wrapping

- Adjust issue list styles so labels can wrap on the same line as the
  text. This relies on `display: inline` with the HTML whitespace being
  used as the separator.
- Add global word-break: break-word. This should generally avoid text
  overflows in various places.

* add whitespace to history labels

* use overflow-wrap

* restore word-break rules

* use correct pre

* use better selector for middle align
