extension type's constructor parameter gets a symbol but no documentation can be attached to it

[isoos]

The latest 8.0.13 (and earlier versions) have this result, originally reported at dart-lang/pana#1393

extension type const Celsius(

    /// This text is not in the dartdoc output.
    num degrees) implements num {
}

Celsius.degrees gets into the output both as file (<library>/Celsius/degrees.html) and as part of the searchable API symbols JSON.
Either we shouldn't get a separate symbol, or it should be able to provide some kind of documentation (like in the above case).

Alternatively: is there any way we could detect these symbols just by parsing the JSON file?

Dartdoc cannot do anything here because neither the RepresentationDeclaration nor any of it's child nodes can have a documentation comment. I've moved this issue to the SDK repo.

Sorry, I didn't read the description closely enough 😊 . Sounds like a dartdoc issue.
