We should double check if we should use the systemPrincipal as the fallback principal in case there is no loadInfo, or if we should create a NullPrincipal. Please check for originattributes and test test_browserElement_inproc_XFrameOptionsAllowFrom.html which used to fail in case we use a nullPrincipal with the wrong origin attributes.
