Overview

Raised by switch_to_frame when the active JS engine can't give the target <iframe> its own browsing context (a real per-frame realm). Only the V8 engine (rusty_racer) builds per-frame realms; under QuickJS the frame stays a same-realm fallback we can't route DOM ops into, so within_frame is unsupported there.
