TOC does not update correctly when the heading is a "short link"

[unional]

Problem

- [Heading 1](#heading-1)

## [Heading 1]

[Heading 1]: http://some-link

When saved, the table to content changed to:

- [[Heading 1]](#heading-1)

## [Heading 1]

[Heading 1]: http://some-link

Which is incorrect.

Here is an example: https://github.com/justland/just-web/tree/main/libraries/react

We are still arguing about it. See
#903 (comment)

thx. but in this case it is not LaTeX math, but supported github markdown syntax.

Understand that it is probably a minor use case. For now, I'll change the usage to avoid the issue.

Just wanted to pointed out the issue. thx! 🌷

Different symptoms, but essentially the same topic:

How to generate TOC visible text. What to escape or remove.

In 2021-01 (January, 2021), I pushed a change (#877) to the development build which requires the text to be:

The rich text (single line Markdown inline without raw HTML) representation of the rendering result (in strict CommonMark mode) of the heading.
This must be able to be safely put into a [] bracket pair without breaking Markdown syntax.

However, a user soon found it breaking extended inline syntax (math). (#903)

• I insist on knocking out any potentially dangerous pieces.
• The user believes it's bug to not respect extended syntax.
• Zhang is confused.

This is not the first time that users raise opposite requests. But the impact is too great.

So, stuck. The change has not been release, just lying in the codebase silently.
