@preact/signals-react value changing didn't call rerender components #500

It's working fine on 1.3.6 version, but after update to version 2.0.0 expected behavior is broken. Example

It’s will work only with Preact, but for React you should use Babel plugin or function “useSignals()” for make a component reactive.

import { useSignals } from "@preact/signals-react/runtime";

const count = signal(0);

function CounterValue() {
    useSignals();
    return <p>Value: {count.value}</p>;
}
