+ REGRESSION: JSObjectSetPrototype() does not work on result of JSGetGlobalObject()
+ https://bugs.webkit.org/show_bug.cgi?id=135322
+
+ Reviewed by Oliver Hunt.
+
+ The prototype chain of the JSProxy object should match that of the JSGlobalObject.
+
+ This is a separate but related issue with JSObjectSetPrototype which doesn't correctly
+ account for JSProxies. I also audited the rest of the C API to check that we correctly
+ handle JSProxies in all other situations where we expect a JSCallbackObject of some sort
+ and found some SPI calls (JSObject*PrivateProperty) that didn't behave correctly when
+ passed a JSProxy.
+
+ I also added some new tests for these cases.
