Steps to repro:

1. Create new project and scene in URP;
2. In Hierarchy right click and select Light>Light Probe Group;
3. In the Scene view move the created probe group by using transform gizmos;
4. Observe the light probe cells and gizmos in the Scene view.

Expected result:
Only light probe cells of the recently added light probe group are rendered.

Actual result:
Additional light probe gizmos are rendered at (0,0,0). See attached screenshot and video.
Regression introduced in Unity 2021.2.0a16.

Notes:
- Reproduces in Version 2021.2.0a16 (663b19a0829e), 2021.2.0a17.2350 (8db971126f68)
- Not reproduces in Version 2021.2.0a15,
- Disabling or toggling light probe group visualization doesn't work as expected - probe or cell visualization cannot be disabled;
- Starting from Version 2021.2.0a16 the rendering is broken - none of the gameobjects and skybox is not rendered;
- Reproducible only in URP; Could not repro in HDRP or built-in legacy RP;
- The following error is being spammed in the Console when creating new project in URP: NotSupportedException: ForwardRendererData has been deprecated. Use UniversalRendererData instead - might be another possible bad symptom of the root cause.
