Escaped CheckBox lists are rendered wrong

[hoijui]

Description

... rendered wrong, according to my expectation, and compared to GitLab and GitHub.

Strictly speaking, the normal check-box-list syntax (which is an extension to standard Markdown):

- [x] a
- [ ] b
- [x] c
- [ ] d

conflicts with the Reference-List syntax (which is standard Markdown):

This is a reference link: [x]

[x]: https://github.com/go-gitea/gitea

This is an issue, for example when using link-checkers (my case),
or if one actually wants to use a reference link [x] (somewhat hypothetical).
To prevent this, both GitHub and GitLab support escaping the square-brackets for check-box-lists, like so:

- \[x\] a
- \[ \] b
- \[x\] c
- \[ \] d

This works great, as my link-checker does not pick these up as (broken) Reference-Links anymore,
and the Git* sites and my local editor renders them just the same.

... Gitea does not, though. It shows a greek X letter as image in the middle of the screen -
I guess some sort of math-rendering thing.
