Remove whitespace inside rendered code <td> (#17859)

This extra whitespace caused isses in Firefox where it would copy a
extra space character at the start and the end. Additionally, in Chrome,
the text selection indicated a spaced on the end of the selection where
there was none. Both issues are fixed with the removal of whitespace.
