this link is broken when adding it through clicking Hyperlink icon in the edit form.
If I instead paste the link directly as is, then it's working fine, like this:
As Oded user noted in a comment, the bug seems to be the markdown renderer encodes : on the URL when it shouldn't .
So, do you know if StackOverflow engine uses some open source library to format the markdown code?
so I can take a peek at fixing the bug (I love fixing the bugs I hit myself)..
