Reviewed by Pascoe.

When loading any https resource in a site-isolated https iframe, we would hang the process
because foundMixedContentInFrameTree doesn't update its document pointer in the loop.
This makes the load succeed so we can investigate other things with site isolation, with
future work to be done to make the mixed content checks actually correct.
