I just realized that this way shouldDisplay is documented as static member
rather than a method of the module:
https://adblockplus.org/jsdoc/adblockpluschrome/module-notificationHelper.html

Also see: http://usejsdoc.org/howto-commonjs-modules.html

Mind writing a follow-up patch to fix that? I'd go for:

  let shouldDisplay =
  /**
   * ...
   */
  exports.shouldDisplay = function()
  {
    ...
  };

We already do it that way in other modules.

+function shouldDisplay(method, notificationType)
+{
+  let methods = displayMethods[notificationType] || defaultDisplayMethods;
+  return methods.indexOf(method) > -1;
+}
+
 NotificationStorage.addShowListener(showNotification);
