Vscode-markdown: Table of contents creation fails when some lines begin with tab

[bugrasan]

What is the problem?

Table of content creation fails with the following error, when code block is indented in ordered list:

Cannot read property '1' of null

How can I reproduce it?

VSCode: v1.41.1
OS: Linux
Markdown All in One: v2.7.0

Copy and paste the following markdown into a file, e.g. test.md:

# first header



## Second header

1. test line1
2. check if works as expected:
    ```bash
    # comment
    ls
    ```

then try to add TOC on line 3 and you will receive the error above.

Is there any error message in the console?
