setState callback is not executed when working with subscriptions on behaviorsubjects/observables

Describe the bug
setState callback is not executed when working with subscriptions on behaviorsubjects/observables

To Reproduce

    componentDidMount() {
        // this logs 'test 1: true' to the console
        this.setState({ test: true }, () => { console.log('test 1 : ', this.state.test)})

        this.dataService.configuration$.subscribe(data => {
            // this correctly logs the data received from the subscription
            console.log('test 2 : ', this.data)
            this.setState({
                data: data,
            }, () => {
                // this is never logged
                console.log('test 3 : ', this.state.data)
            });
        });

        // this is also never logged
        this.setState({ test: true }, () => { console.log('test 4 : ', this.state.test)})

        // this correctly logs the data from the state
        // proving that the state is set correctly but the callback is never executed
        window.setTimeout(() => { console.log('test 5: ', this.state.data)}, 1000)
    }

The setstate callback is never executed when called from within a subscription or after a subscription.
It works fine before the subscription, and the state is always set correctly.
When using v 10.5.14 this works fine.

Expected behavior
I would expect the setstate callback to run within or after subscriptions.
