Not able to pass id's to heading tag

[mayankbytes]

"### My Great Heading {#custom-id} "

should be converted to following according Markdown document

"< h3 id="custom-id">'My Great Heading </h3 >"

but using react-markdown, it is getting converted to
"< h3 > My Great Heading {#custom-id}</h3 >"

@rexxars - Do we have any way by which I could achieve this?

I found:

• getCoreProps does not pass additional props but only extracts a source position
• Heading renderer does not pass additional props neither

As a solution I would either split props or pass the rest to renderer. Although, I see no additional props passed by plugins.

This is not a feature of markdown, and as such would not be supported in core.
However it can be added through a remark plugin by adding https://github.com/imcuttle/remark-heading-id
