Passthrough with "[[" and "]]" delims

Using:

goldmark:
  renderer:
    unsafe: true
  extensions:
    passthrough:
      enable: true
      delimiters:
        inline:
        - ["[[", "]]"]
        - ["@@", "@@"]

I can’t get my passthrough render hook to work with the square bracket set of delims. If I use “@@” it works fine. That is, I can use both delims on the same page and only the @@mytext@@ one invokes the render hook. I can’t see anywhere in the docs to suggest this wouldn’t be possible, but maybe I’m missing something?

I suspect [foo] and even [[foo]] will be detected as a link (which in the parser has a higher priority than the passthrough extension.

Makes sense, but should this considered a bug with either the implementation or the documentation?
