[Bug] 9.0.1: Deck.pickObject with unproject3D==true returns a 2d coordinate

Description

After upgrading to 9.0.1 (from 8.9.32), Deck.pickObject does not seem to work correctly anymore with unproject3D==true. It returns a 2d [lng,lat] coordinate instead of a 3d [lng, lat, alt] one. Downgrading back to 8.9.32 fixes it.

Flavors

[ ] Script tag
[ ] React
[ ] Python/Jupyter notebook
[ ] MapboxOverlay
[ ] GoogleMapsOverlay
[ ] CartoLayer
[ ] ArcGIS

Expected Behavior

Get a pick with a 3d coordinate [lng, lat, alt]
