Neat

It would be nice in the future if this aligned with the new test harness used by
protocol, which looks almost the same: testRunner.startHTML(html, description)

This code is actually almost the same as page.loadHTML
(https://cs.chromium.org/chromium/src/third_party/WebKit/LayoutTests/inspector...)

startHTML is kicking off the test (starting the debugger session) & creating the
DOM fixture vs. this method is only about creating the DOM fixture.

+  return TestRunner.evaluateInPagePromise(`document.write('${html}');document.close();`);
