bug? — OrbitControl.tween not calling finishCb if the camera is already there

verge version 3.3.1
file OrbitControls.js, line 322

if the camera is already in the requested position
the code return without playing any animation,
but the finishCb is not called.

I don’t know if this is the intended behavior,
but if you are to chaining some animation together
this is a bit annoying.

best regards and thanks for your great work.
