Methods assigned to `exports` get "Unresolved function or method" warning

[AllieCR]

Description

If you use requireJS in the CommonJS style and add a method the exports parameter it provides, Webstorm will not be able to resolve that method if you attempt to use it elsewhere. However, this problem does not occur if you use module.exports instead of just exports.

Example

// JustExports.js
define(function(require, exports) {
  exports.someMethod = function() {};
});

// ModuleDotExports.js
define(function(require, exports, module) {
  module.exports.someMethod = function() {};
});

// UseExports.js
define(function(require) {
  var JustExports = require('JustExports');
  var ModuleDotExports = require('ModuleDotExports');

  // If you mouse over `someMethod` here, Webstorm shows the warning 
  // "Unresolved function or method someMethod()"
  JustExports.someMethod();

  // If you hold down the Cmd key and mouse over `someMethod` here, Webstorm turns the
  // cursor into a pointer and tells you where the method lives. If you click on it,
  // Webstorm will take you to the method definition.
  ModuleDotExports.someMethod();
});
