Inline macro located at the beginning of a non-first paragraph of a list item gets a truncated name in CommonMark Markdown 1.2

When an inline macro is the first content of a paragraph that isn't the first one of a list item, the macro name and parameters are not parsed correctly.

Steps to reproduce: parse the following markdown/1.2 content:

* a

  {{info title="b"/}}

Expected: an info macro with the parameter title=b.
Actual: a macro named in with a parameter fo= (the list item indentation is not taken into account when reading the macro).
