Describe the bug
The heuristics are now creating a problematic series of space-views in the objectron example.

First there is a 2d "world" view.
Then there is a nested grid container with the expected 3D world view and 2D camera view.

To Reproduce
Go to: https://app.rerun.io/version/0.12.0-alpha.4/index.html

Load the objectron example.
