Mention is created every time someone uses "#<number>" (e.g. "#123") in the text of issue or in the comment, where number is a sequential number of issue or pull request . When comment is published in issue A which mentions issue B, there is a pseudo-comment added to B, and subscribers of B receive email notification.

For example, may the force be with you if someone pastes gdb or lldb backtrace into comment without escaping it into markdown raw text block (```). Also, GitHub parses mentions in git commit messages, so care must be taken to avoid any occurrences of "#<number>" with a meaning different from reference to issue number.
Yeah, this is a pretty significant functional regression to me. I use
bug dependencies all the time (e.g.
and not having this capability will significantly hinder my ability to
track & triage some bugs.

You probably like this feature of Bugzilla when you can attach self-contained HTML file to the issue and then simply open it by URL in any browser including your build of WebKit to try it out. Forget this - GitHub simply forbids HTML or JS attachments (without wrapping them in archive):

This is another massive functional regression. I open test cases on
Bugzilla without downloading all the time, not to mention that it's a
great way to test iOS devices as well. Not being able to do that would
significantly reduce my productivity.
