Wrong source type for generated type ODataModel$DataReceivedEvent

The problem rather is that the TypeScript signatures (and the JSDoc comments that they're based on), do not (and IMO cannot) reflect event bubbling. It cannot in general be foreseen what child fires an event that then bubbles up and can be listened to on an ancestor.

The only solution that comes to my mind is to remove the typing of the getSource again. This would be similar to browser events that also can't say of what type the original target of an event could be. It depends on the DOM hierarchy.

Unfortunately, the ability for an event to bubble up is decided on the original event source. Therefore, the ancestor cannot even know (with the information that we currently have) if there's a descendant that fires the same event and allows it to bubble up.

In the case of the ODataModel, the different entities luckily know each other. Maybe we find a less impacting solution for that scenario. But in the general case, I don't see how we could type getSource better than with EventProvider, which would be cumbersome in most cases.
