The PR is working fine when GLB file is loaded.

It seems to break something when scene is imported with GLB file. After a scene is imported with GLB file, docker compose down; docker compose up -d sequence results in web container failure (I checked it on OOB Queuing scene with GLB file loaded as a map - scene export, scene & cameras removal, scene import, deployment restart).

I haven't debugged it deeper but this issue is not reproducible on main, so it is apparently introduced by the PR changes.
