code: function dispatchToStores(ids = new Set()) {
  	ids.forEach((storeID) => {
  		if (this[IS_PENDING][storeID]) {
  			return true;
  		}
  
  		invokeCallback.call(this, storeID);
  	});
  }
docs: This method takes an array of store id's and iterates
  over them to determine if we should invoke a dispatch
  of the action.
