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.
