Get parameter hints for JSDoc documented function expressions

Please consider this little snippet:

const r = require('rethinkdb');
const util = require('util');


/**
 * @function createTable
 *
 * Creates a table
 *
 * @param {string} database
 * @param {string} tableName
 * @return {Promise}
 */
const createTable = util.promisify(function(database, tableName, callback) {
 r.db(database).tableCreate(tableName).run(connection, callback);
});

My problem is: although I have properly annotated createTable with JSDoc comments, it does not seem to be recognized as a function by the IDE. There is no parameter hinting, and when auto-completing it does not even insert a pair of parentheses. Curiously enough, Quick Documentation shows the parameters just fine.

Am I missing something? Is there any other way to make the IDE understand that createTable is function?
