Description
As a result, upsampled tiles end up rotated 90 degrees.
Contributor guide
Research direction
Start by locating the upsampling path that handles tileset.json and glTF coordinates, then trace how gltfUpAxis is interpreted during the operation. Confirm the current behavior with a case that produces the reported 90-degree rotation; done means upsampled tiles preserve the source coordinate orientation.
