Choosing Resolved as the case status on the open case form does not populate the end date

Create a new case. Choose Resolved in the case status field. After saving the case has no end date.

Either it should not let you choose Resolved at open time, or else it should have the same effect as the Change Case Status activity. I can think of situations where either might be the desired behavior, so not sure which is preferred. There are some organizations that might have cases where you take a call and then you're done, so it might be convenient to leave it available on the open case form.
