Typescript: withObservables does not properly check types

[larkox]

Let a component like:

const myComponent = ({myList: string[]}) => {
    ...
}

If we pass a more general within withObservables, instead of typescript complaining, it appears as valid:

const wo = withObservables() => {
    const list: Observable<(string|number)[]> = ...
    return {myList: list}
}

Expected result:
Some error saying that types are not compatible, since the return type of withObservables ((string|number)[]) is not assignable to the props (string[]).

Some other examples:

• Props: string, withObservables return: string|undefined.
