// The quest for a TEST_ROOT: we have to choose a way of addressing the RDM document
// such that two things can happen:
// 1) addRDMTask can load it.
// 2) WindowSnapshot can take a picture of it.
// The WindowSnapshot does not work cross-origin. We can't use a data URI, because those
// are considered cross-origin.
// let TEST_ROOT = "";
// We can't use a relative URL, because addRDMTask can't load local files.
// TEST_ROOT = "";
// We can't use a mochi.test URL, because it's cross-origin.
// TEST_ROOT =
// "http://mochi.test:8888/browser/devtools/client/responsive/test/browser/";
// We can't use a chrome URL, because it triggers an assertion: RDM only available for
// remote tabs.
// TEST_ROOT =
// "chrome://mochitests/content/browser/devtools/client/responsive/test/browser/";
// So if we had an effective TEST_ROOT, we'd use it here and run our test. But we don't.
// The proposed "file_meta_1000_div.html" would just contain the html specified below as
// a data URI.
// const TEST_URL = TEST_ROOT + "file_meta_1000_div.html";
// Instead we're going to mess with a security preference to allow a data URI to be
// treated as same-origin. This doesn't work either for reasons that I don't understand.
