@import syntax in a javascript file to get types from a typescript file

[stwlam]

I defined a type like so in a file called "types.d.mts":

export interface Thing {
  foo: number;
  bar: string;
}

In a javascript file, I imported it using the relatively new @import syntax:

/**
 * @import {Thing} from "./types.mjs";
 */

class MyClass {
  /**
   * A thing.
   * @type {Thing}
   */
  thing = {foo: 0, bar: ""};
}

VSCode picks it up just fine:

But typedoc doesn't generate Thing's definition (no link):

Is this a feature gap, or are there certain steps necessary to follow?
