#8599 show domain on external links, if misleading
When showing links (e.g originating from markdown, but really any html output) we should do something about links that could be misleading. For example with <a href=https://evil.com/>sourceforge.net/auth/</a> we could automatically append (evil.com) into the output so its obvious when its misleading.
We should also check for non-ascii domain names (IDN) and if they have chars that are potentially confusing with normal ascii, then show the decoded domain name (even if the link & text match, if the chars could be confusing)
