GLTF 302 Redirects not taken into account when loading assets

[benferns]

Description

Requesting a gltf file that resolves via a 30X redirect doesn't rewrite relative asset paths to that new location, resulting in 404s.

Example:

1.gltf has image 'image.png' stored in same directory

Request: api.example.com/models/gltfs/1 Response: 302 cdn.example.com/gltfs/1.gltf

Model Viewer: 404 api.example.com/models/gltfs/image.png

Note that Scene Viewer on Android handles the redirect correctly.
