Hello, I was trying to have subsections that are actually hyperlinks to other documents but the ToC generates my subsections with nested looking hyperlinks that are not working.

Steps to reproduce:

1. After the comments, generate an H1 with some text.
2. Generate an H2 under the H1 text.
3. Convert the H2 section to a hyperlink to some resource.
   e.g:

# My H1 section
## [My H2 section](www.example.com)

Expected ToC:

- [My H1 section](#my-h1-section)
    - [My H2 section](#my-h2-section)

Actual ToC:

- [My H1 section](#my-h1-section)
    - [[My H2 section](www.example.com)](#my-h2-section)

Is there a workaround for this issue?
