Hi! I'm loading a glTF model (San Francisco OSM buildings extruded, in 3857 projection (Web Mercator)

I'm struggling to find the correct way to get things georeferenced right.

Actual Result

Model needs to be scale to a weird 0.79 factor to get well positioned.
Here is what it looks like with a 1 scale
image

Expected Result

Scale should be 1 as base layer is a 3857 map from MapBox, or native 4326 coordinates (lat/lon) should be supported.

Reproduce Steps

Editor URL : https://codesandbox.io/s/gltf-nebulagl-vo7mi?fontsize=14&hidenavigation=1&theme=dark
Model bbox : Xmin: -13626844.045070592, Xmax: -13626364.313725019, Ymin: 4552046.34776861, Ymax: 4552229.3712238865, Center: -13626604.179397807, 4552137.859496249
