[Mobile] AR Foundation XR tracked distance between two objects changes when moving the mobile device around
How to reproduce:
1. Open the “IN_78715” project
2. In the build Settings “Run Device” dropdown, select the desired device
3. Press Build And Run
4. Point the phone to the physically placed markers (“marker1.png”, “marker2.png”) and wait until the app detects both of them (when detected text appears on both of them “Detected“)
5. Observe the distance between markers shown in the right corner
6. Move the phone further back or to the sides
Expected result: Shown distance between markers doesn’t change when the device is moved
Actual result: Shown distance changes

Notes:
- For the markers I used “marker1.png” and “marker2.png” printed on the paper since it was better detected than images displayed on other devices
- Also reproducible on the iOS platform

It is important to use high quality images to get stable tracking. Google's arcoreimg tool can be used to find the quality score for an image, and they recommend using images with a score of at least 75.
