Relative URLs in readme markdown starting with `./` render broken

Relative URLs in readme markdown starting with ./ should link to files within the package, but incorrectly deno.land renders them as if they are deno.land/x packages.

Here is an example readme with broken relative URLs (the top logo SVG, and various links to package modules):

https://deno.land/x/ruck@v1.0.0

Similar to a past issue (that was apparently fixed) for relative URLs that don’t start with ./:

It seems that in DisplayFile.tsx when rendering a markdown file the baseUrl prop is missing.

https://github.com/denoland/dotland/blob/46462c8a3c3ca830d49dfa110f26d3231231d334/components/FileDisplay.tsx#L114-L127

However in Markdown.tsx the baseUrl prop is optional but later is used to call the gfm function.

https://github.com/denoland/dotland/blob/46462c8a3c3ca830d49dfa110f26d3231231d334/components/Markdown.tsx#L4-L16

As part of the solution, I tried to add the baseUrl prop, but it still doesn’t work

baseUrl = {props.baseURL}

Conclusion

It seems that the problem is related to the gfm function that treats the markdown. This is a dependency linked to crowlKats/deno-gfm repo. There are some custom changes to the links. A think here is where the problem is.

https://github.com/crowlKats/deno-gfm/blob/663b1cc026ac881b2fe8928f157db0126ee08dba/mod.ts#L29-L34

 link(href: string, title: string, text: string) {
    if (href.startsWith("#")) {
      return `<a href="${href}" title="${title}">${text}</a>`;
    }
    return `<a href="${href}" title="${title}" rel="noopener noreferrer">${text}</a>`;
  }

I might be misunderstanding the code, but it looks like maybe the operation done here also needs to be done on the baseURL passed to FileDisplay:
