A page using the WebUSB API shouldn't be frozen and shouldn't enter the
BackForwardCache.

When navigating away from a page:
 1) The USB connection should be released.
 2) The tab indicator should be removed.

This won't happen if the RenderFrameHost is kept in the back-forward
cache.

Some background on why we sometimes need to disable bfcache:
