Also tested on a different device with v33.1 from the Google market, same bug.

Desktop Firefox works fine however.

Android kills the browser alongside every other process due to memory constraint issues with this demo

I tested the demo page today in Firefox on a 4G A51 and it gets out of the tunnel without a problem. I think we can close this bug out at this point.
