Automatic update from web-platform-tests WebSocket: stop removing an iframe in onerror from crashing There was an issue that if the iframe owning a WebSocket was synchronously removed in the onerror handler then it would crash the render process. This was caused by unconditionally calling Close() without checking the current state. Fix it. Also add a web platform test.
