If a LayoutTest calls pauseTransitionAtTimeOnElementWithId() with an unrecognized property name, like: layoutTestController.pauseTransitionAtTimeOnElementWithId("foopy", 0.5, "target"); it asserts here: ASSERTION FAILED: !HashTranslator::equal(KeyTraits::emptyValue(), key) (/Volumes/InternalData/Development/webkit/WebKit.git/WebKitBuild/Debug/JavaScriptCore.framework/PrivateHeaders/HashTable.h:455 void WTF::HashTable<Key, Value, Extractor, HashFunctions, Traits, KeyTraits>::checkKey(const T&) [with T = int, HashTranslator = WTF::IdentityHashTranslator<int, std::pair<int, WTF::RefPtr<WebCore::ImplicitAnimation> >, WTF::IntHash<unsigned int> >, Key = int, Value = std::pair<int, WTF::RefPtr<WebCore::ImplicitAnimation> >, Extractor = WTF::PairFirstExtractor<std::pair<int, WTF::RefPtr<WebCore::ImplicitAnimation> > >, HashFunctions = WTF::IntHash<unsigned int>, Traits = WTF::PairHashTraits<WTF::HashTraits<int>, WTF::HashTraits<WTF::RefPtr<WebCore::ImplicitAnimation> > >, KeyTraits = WTF::HashTraits<int>])
