Function script::dom::bindings::proxyhandler::cross_origin_has_own

pub unsafe fn cross_origin_has_own(
    cx: SafeJSContext,
    _proxy: RawHandleObject,
    cross_origin_properties: &'static CrossOriginProperties,
    id: RawHandleId,
    bp: *mut bool
) -> bool

Evaluate CrossOriginGetOwnPropertyHelper(proxy, id) != null. SpiderMonkey-specific.

cx and proxy are expected to be different-Realm here. proxy is a proxy for a maybe-cross-origin object.
