No completions in `@param` tag missing parameter name

You can probably whittle this down to a 2 file repro, but just install @azure/functions in a plain .js file and try to write the following code:

// @ts-check

/**
 * @param {import("@azure/functions").$}
 */
module.exports = async function (context, req, connectionInfo) {
  context.res.json(connectionInfo);
};

Remove the $, place your cursor there, and request completions.

Expected: Completions
Actual No completions, maybe because the parse isn't failing gracefully.

Reproduce the issue in a plain .js file with @azure/functions installed, using the @ts-check and @param example from the report. Place the cursor where the parameter name is missing and request completions; done means completions appear instead of the parser failing without results.
