Custom collisions with moveTo

Does anyone know if a t2dTileLayer::onCollision is bypassed when the collision occurs through a moveTo on a static sprite? All collisions work as expected when I move the player object using the keyboard (setLinearVelocity), but are completely ignored when I use the mouse.

Has anyone else run in to this, or am I just doing something so horribly wrong that the universe just might become undone?
