Noop when document.open is called during iframe parsing

Browse Source 
I'm not sure what the correct behavior is, but this fixes a WPT crash:
/html/browsers/sandboxing/sandbox-inherited-from-required-csp.html

The issue is iframe-specific as, with an iframe, you document.write can be
called during parsing when there's no document._current_script (because it's
being executed from the parent).
