 <!-- Can't use absolute path below for mock-interaction.js.
 Web component tester(wct) has a built-in http server and it serves "/components" directory (which is
 actually /node_modules directory). Also, wct patches some files to load modules from /components.
 With the absolute path, browser tries to load dom-module from 2 different places (/component/... and
 /node_modules/...) though this is actually the same file. This leads to a run-time error.
