When using marked-terminal 7.1.0 with marked 13.x, I'm seeing something like:

*   **bold** inside a list item

not transform the bolded text, instead just rendering the double-asterisks directly to the terminal. This was not the case with marked 11.0.1.

My guess is something with the expected AST changed and marked-terminal isn't picking it up.

It may be useful to at least flag this as a known issue with later versions of marked.
