Feature request: useObservable to return the instant value on Component initialize if Observable has sync value

[gyz0072004]

In my component, I use an useEffect to do some initialization with side effect.

const title = useObservable(() => titles$);
useEffect(() => {
    // do initialization with title
}, []);

title$ is a BehaviorSubject, so I would like the useEffect block can get the current title value directly, so that I don't need to wait another cycle for the initialization.

I also need it. The above code may solve your problem.
