Comment (by SergeyBiryukov):

 [attachment:"47244.3.diff"] builds on @birgire's patch from #46316 and
 fixes both tickets. Might need a refresh if #46316 is committed first.

 The patch ensures that `rel` attribute is added with the correct quotes:
 * if `target='_blank'` has single quotes, then `rel='noopener noreferrer'`
 has single quotes too.
 * If `target=_blank` does not have quotes (as in the example above),
 quotes of the `rel` attribute are checked as a fallback.
