Revert "Reduce width when vertical TOC shows up"

This reverts commit d7ed308f3c23debc72e1030189b6821898c62b44.

The site's styles are broken and use em sizes all over the place,
which blows up on UAs that override our font size. Reverting this,
with the original issue to be fixed with BS conversion.
