Doesn't work with variables (mdx-bundler)

[CanRau]

I'm using mdx-bundler#frontmatter-and-const and define my h1 as

# {frontmatter.title}

which in the ast looks like

{
  "type": "element",
  "tagName": "h1",
  "properties": {},
  "children": [
    {
      "type": "mdxTextExpression",

which is not compatible with toString(node) (I guess), but changing value: toString(node) to value: node doesn't seem to be compatible with valueToEstree

Any idea how it could be made compatible? If you have the time and interest of course 😇

hmm, i think we would need a way to evaluate the estree at compile time. or create the tree ourselves instead of using valueToEstree (which sounds more doable).
