// TODO(dmfilippov): remove bundled-polymer.js imports when the following issue
// https://github.com/Polymer/polymer-resin/issues/9 is resolved.
// Because gr-diff.js is a shared component, it shouldn' pollute global
// variables. If an application wants to use Polymer global variable -
// the app must assign/import it and do not rely on the Polymer variable
// exposed by shared gr-diff component.
