Different conversion from DaringFireball and Commonmark compared to Gith-Hub

[carloBarazzetta]

First of all, congratulations for the library.
I integrated it in this project:
https://github.com/EtheaDev/MarkdownShellExtensions
to be able to edit .md files with an editor and have a preview in Windows Explorer.
Using files edited in Git-Hub I noticed that using the Commonmark dialect I can render the tables correctly but not the notes.
Using the DaringFireball dialect the tables are no longer rendered correctly but the notes are correct.
Is it not possible to use a "mix" of the two dialects to obtain the same rendering that is obtained in Git-Hub?

Here an example with CommonMark:

thank you.
