JSDoc function type not parsed correctly when nested

[weswigham]

TypeScript Version: 2.7.0-dev.201xxxxx

Code

  /**
   * @param {!Runtime.Extension} extension
   * @param {?function(function(new:Object)):boolean} predicate
   * @return {boolean}
   */
  _checkExtensionApplicability(extension, predicate) {
    return false;
  }

Expected behavior:
Strong types for extension and predicate.

Actual behavior:

front_end/Runtime.js(398,24): error TS1138: Parameter declaration expected.

(An error on the inner function, rather than a correctly constructed type)

Another example with a nested function type which also parses badly:

CookieTable.CookiesTable = class extends UI.VBox {
  /**
   * @param {function(!SDK.Cookie, ?SDK.Cookie): !Promise<boolean>=} saveCallback
   * @param {function()=} refreshCallback
   * @param {function()=} selectedCallback
   * @param {function(!SDK.Cookie, function())=} deleteCallback
   */
  constructor(saveCallback, refreshCallback, selectedCallback, deleteCallback) {
 }
}
