It looks like this change may have caused new API test failures on ios-simulator <https://build.webkit.org/builders/Apple%20iOS%209%20Simulator%20Release%20WK2%20%28Tests%29/builds/3185> Tests that failed: WKUserContentController.AddUserStyleSheetAfterCreatingView WKUserContentController.AddUserStyleSheetBeforeCreatingView WebKit2.BundleParameters Tests that timed out: WKWebView.LoadAlternateHTMLStringFromProvisionalLoadError WebKit2.RemoteObjectRegistry

I ran API tests with and without this change locally, and it does appear that it causes the failures.
