When pasting Markdown, there is no token info.
eg
# hello world
I'm a paragraph
So there is something I'm not understanding.
In Content Block, each instance is it's own thing. So there's no way to apply some universal token to a certain instance.
On the other hand Content
Embed or Markdown Embed supports styling the children.
The key differentiator is Content Block inserts new independent instances and Content Embed just applies CSS selectors to the code and no instances are involved as its custom code.
