/**
 * @assertion Stream errors
 *   Returns a broadcast stream of uncaught errors from the isolate.
 *   Each error is provided as an error event on the stream.
 *   The actual error object and stackTraces will not necessarily be the same
 * object types as in the actual isolate, but they will always have the same
 * Object.toString result.
 *   This stream is based on addErrorListener and removeErrorListener.
 *
 * @description Check that errors stream is a broadcast stream.
