/* Any copyright is dedicated to the Public Domain.
/* This test records which services, frame scripts, process scripts, and
* JS modules are loaded when creating a new content process.
*
* If you made changes that cause this test to fail, it's likely because you
* are loading more JS code during content process startup. Please try to
* avoid this.
*
* If your code isn't strictly required to show a page, consider loading it
* lazily. If you can't, consider delaying its load until after we have started
* handling user events.
