Here: Allowing whitespaces in link URLs - #4 by ClikCode in 2018 @jgm wrote: I’ve already made the change allowing whitespace inside <...> links. But if I open commonmark.js demo and try <http://hyper.link/with spaces> there, it is rendered as is, that is, as <http://hyper.link/with spaces>. That is, as plain text, not as a hyperlink. Why is that?
