[Bug] Terrain has a weird behavior on zoom.

[abdallah-yassin-sager]

Description

When using the Mapbox terrain layer, zooming in closely causes markers to behave inconsistently — they flicker or jump back and forth instead of staying stable.

This is a screenshots:

And this is the code:
<Map key={mapBoxStyle} ref={mapRefCallback} mapboxAccessToken={mapBoxAccessToken} initialViewState={viewport} mapStyle={mapBoxStyle} onMouseMove={onMouseMove} onMove={evt => setViewport(evt.viewState)} onMouseEnter={onMouseEnter} onMouseLeave={onMouseLeave} projection='globe' onClick={onClick} onContextMenu={onContextMenu} interactiveLayerIds={['docks', 'drones']} terrain={{ source: 'mapbox-raster-dem', exaggeration: 1, }} // maxZoom={19} > <Source id='mapbox-raster-dem' type='raster-dem' url='mapbox://mapbox.mapbox-terrain-dem-v1' tileSize={512} maxzoom={20} /> </Map>

Expected Behavior

Markers should remain stable and fixed in place when zooming.

Steps to Reproduce

1. Enable the terrain layer.
2. Zoom in deeply on the map.
3. Observe the marker positions.

Environment

• Framework version: "react-map-gl": "^8.0.1",
• Map library: Mapbox (mapbox-gl)- "^3.9.4",
• Browser: Chrome and Firefox.
• OS: Mac and Linux.
