camera constraint bug?

I have a model that is positioned relative to the camera, like so:

function posRelativeToCam(Cesium, camera, offsetHeight=3) {
	return Cesium.Cartesian3.fromRadians(
		camera.positionCartographic.longitude,
		camera.positionCartographic.latitude,
		camera.positionCartographic.height - offsetHeight
	);
};

// [...]

const listener = () => {
	entity.position = cesiumHelpers.posRelativeToCam(
		Cesium, 
		camera, 
		3
	);
};
camera.changed.addEventListener(listener);

I would expect it to always be upright, however I see this happen → screen capture: https://vid.me/IuMk

@freder part of the probem you're seeing is this bug where the camera gets stuck if you're using zoom limits #3984

The bug about zooming to the wrong location is a new one, so thanks for reporting that!

actually, I doubt it's related to #3984 — see https://groups.google.com/d/msg/cesium-dev/YN7Oq2WhJDA/rRjxBc3WCAAJ
