J. Ryan Stinnett 95f8000ac8 Bug 1238160 - Add assertions in non-desktop code paths. r=bz,fabrice
Several code paths try to ask the principal if it's in a browser element, but
the principal now only knows about *isolated* browser elements.  All such code
paths are currently unused on desktop.  The frame loader now asserts that
isolation remains enabled for cases where apps are used.
