cancel Callout When Off Screen
Whether the callout should be fully dismissed when its anchor pixel moves completely outside the mapView rectangle during camera moves (move / CalloutView.moveView).
Default is true:
In-flight inspector work is cancelled.
The callout UI is deactivated and anchor state cleared, but on is not set to
false, so inspector mode stays on and the next map tap can show again.
Set to false to restore the previous behavior: the view becomes View.INVISIBLE off-screen while isActive remains true, preserving timeline refresh without showing the bubble.
