I started taking a look at this bug and found that it could be something to do with the library they're using to parse their markdown. I copied and pasted this into numerous other open source markdown editors and got the same result. Even GitHub's markdown parser results in this:

• [Sub-Header2](#Sub-Header2)

From @malorie16's comment it looks as if this rendering of the TOC is intended as per our markdown renderer. I do, however, think that we should try to fix this issue within the TOC; mostly because it is generated by us.

My suggestion for a fix is that upon generating the TOC we remove all links. That way we can still generate links to jump within the note. Thus preventing this issue with nested links.

#3080 is the exact complement to this issue: Generated link, doesn't handle TOC.
