Does CompositeDisposable.dispose() Interrupt Tasks.await() in an Rx Subscription?

Question

Is it normal for Tasks.await() from com.google.android.gms.tasks to be interrupted when CompositeDisposable.dispose() is called in an Rx subscription? I thought Rx operations run to completion by default.

In other words Tasks.await() throws InterruptedException when the Rx subscription is disposed, I don't understand how and why there are not information about this.

addSubscription(Completable.create(emitter -> {
        try {
            //some operation with Tasks.await()
        } catch (ExecutionException e) {
            e.printStackTrace();
            if (!emitter.isDisposed()){
                emitter.onError(e);
            }
        } catch (InterruptedException e) {
            e.printStackTrace();
            if (!emitter.isDisposed()){
                emitter.onError(e);
            }
        }
        
        if (!emitter.isDisposed()){
            emitter.onComplete();
        }
    }).subscribeOn(getIoScheduler()).observeOn(getMainThreadScheduler()).subscribe(() -> {
        //on complete
    },throwable -> {
        throwable.printStackTrace();
    }));
