Objects slightly shift position after placement (using InstantTracker)

[bennofatius]

Describe the bug
Doing some basic tests atm placing and picking up shapes using InstantTracker. It does generally work, but I noticed that placed objects don't keep their precise position esp. the more and more wildly I move around my phone. If I shake the phone heavily, it will lose its position completely. Just curious if this is just a known shortcoming of this technology more broadly, or if there are ways to improve this?

To Reproduce
Really just a simple Gatsby/React site using a basic structure such as:

<ZapparCanvas >
                <ZapparCamera onFirstFrame={() => setLoaded(true)} />
                <InstantTracker
                    placementMode={placementMode}
                    placementCameraOffset={[0, 0, -10]}
                >

                    <MyMesh />

                </InstantTracker>

                <directionalLight />

            </ZapparCanvas>
