Misalignment of Skeleton Helper and Bounding Box when added to parent group. Fine when added directly to scene

[fuzzy_wobble]

When I add everything directly to the scene (RED) works as expected more or less.

When I add everything to a parent group (BLUE) it’s all completely misaligned.

Any idea why this is happening?

Here is the code example: https://gltf-with-bbox.glitch.me/
