0. Start chromium, navigate to about:tracing (this is just for about:tracing, the bug is perhaps present on all platforms)
1. Navigate to http://www.florajs.com/demos/flap.html in another tab
2. Record a trace, observe it's mostly JS and style recalculation
3. Open DevTools on the demo page
4. Record another trace.
5. Observe we spend 8-9ms per frame in LayerTreeHost::updateLayers now
