Steps to reproduce

mdast-util-gfm-autolink-literal package uses a lookbehind assertion which is not fully supported in Safari iOS. It causes the component to not render (the Milkdown Editor). This package is used by remark itself. I ended up tracing it through the package chains but I don't have it exactly. In any case, this is likely to cause a problem. @wenxue11 has a forked repo you can override for now: https://github.com/wenxue11/mdast-util-gfm-autolink-literal

I wanted to post it as an issue for anyone else looking to see a fix. I know its not something you can fix on this package (I suppose you can override too but that feels worse?) but it sems like a good idea to document the issue and present a solution.

How to override in pnpm (though maybe fork wenxue11's repo)

"pnpm": {
    "overrides": {
      "mdast-util-gfm-autolink-literal": "github:wenxue11/mdast-util-gfm-autolink-literal"
    }
  }

They have changed the regex for iOS compatability:

/** @type {FromMarkdownTransform} */
function transformGfmAutolinkLiterals(tree) {
  findAndReplace(
    tree,
    [
      [/(https?:\/\/|www(?=\.))([-.\w]+)([^ \t\r\n]*)/gi, findUrl],
      -[/(?<=^|\s|\p{P}|\p{S})([-.\w+]+)@([-\w]+(?:\.[-\w]+)+)/gu, findEmail]
      +[/(?:^|\s|[!"#$%&'()*+,\-./:;<=>?@[\\]^_`{|}~])([-.\\w+]+)@([-\w]+(?:\.[-\w]+)+)/gi, findEmail]
    ],
    {ignore: ['link', 'linkReference']}
  )
}

Expected behavior

For it to render the editor.

Actual behavior

Doesn't render the editor.
