Good be nice if we also navigate to some other page here instead of just
about:blank.

For now I would like to land it as-is since that is how the previous test
worked. I would like this CL to be a straight port of the old test and any
improvements/changes to be made in separate CL. I think we should have a
discussion with the memory-infra folks before making any change like this.
