Description

I tried opening the tracing.html page using Google Chrome Version 81.0.4044.138, and the page was blank. Upon inspecting, seems like Chrome no longer supports registerElement

tracing.js:31 Uncaught TypeError: document.registerElement is not a function

This was reported to the Chromium project as https://bugs.chromium.org/p/chromium/issues/detail?id=1036492, which has been closed. We should update the trace viewer version in thirdparty to include whatever fixes are necessary, since tracing is pretty valuable in a pinch.
