Research direction
Start by reproducing the failure with a vector source whose maxzoom is below the terrain max zoom, then trace the height-offsetting logic for circles, symbols, and fill-extrusions across the zoom threshold. Done means these vector layers retain their terrain height offset instead of snapping to zero.
