Repro steps ...
- Start a watchPosition() request
- Wait for the success callback to be called
- Start a getCurrentPosition() request

Providing a position is obtained, the watchPosition() success callback is called as expected. When the getCurrentPosition() request is made, its success callback should be called with the same position. Instead, it is not called until an updated position is obtained.

The spec [1] states that if the location acquisition process is successful, we should invoke the success callback. In this case, when we make the getCurrentPosition() request, a successful location acquisition process is already ongoing, and I think it makes sense to use the already obtained position for the success callback. This matches the developer's expectation that a getcurrentPosition() request should be independent of any ongoing watchPosition() requests.

The problem is that GeolocationController only informs the GeolocationClient when the first request is made and the when the last request ends. It does not inform the client about new requests made while other requests are ongoing.
