  React.useInsertionEffect(() => {
    initShiki().then((highlight) => {
      setHtml(highlight(content));
    });
  }, [content]);

  useInsertionEffect(() => {
    const popCb = () => {
      const newVal = parse(filterUnknownParamsClient(defaultState));
      state.current = newVal
    };

    window.addEventListener(popstateEv, popCb);

    return () => {
      window.removeEventListener(popstateEv, popCb);
    };
  }, []);

  useInsertionEffect(() => {
    const cb = () => {
      _setState(stateMap.get(stateShape.current) || stateShape.current);
    };
    const unsub = subscribers.add(stateShape.current, cb);

    return () => {
      unsub();
    };
  }, []);
