Using markdonw in text of a checkbox don't work

[Yivan]

Describe the bug
Using markdonw in text of a checkbox don't work, in preview mode and on the final page too.
Bold, etc. don't work too.

To Reproduce
On an edit page with markdown editor, fill:

* [ ] The sun is high in the `sky` + `here`
* [ ] The sun is high in the sky + here

Result is:

Same bug on final page rendering, than preview mode.

Expected behavior
A correct markdown (we used GitLab wiki before, and this worked correctly).
Here the checkbox is replaced by a list and the "+" double the sentence strangly.

Host Info (please complete the following information):

• OS: Docker
• Wiki.js version: 2
• Database engine: postgres

Thanks.

I could reproduce this using the latest development version. I tested your example using the markdown parser we use's demo page, so the issue seems to be with our implementation.
