[Bug] Uncaught TypeError: Cannot read properties of undefined (reading 'key') with terrain

Description

I'm getting this error when I zoom or pan quickly and terrain is present in my style. I've tried setting maxTileCacheSize to 256 to no avail. Removing the terrain object from the style stops this from happening.
The terrain source is https://api.maptiler.com/tiles/terrain-rgb/tiles.json

    at e.Map._render (map.ts:3291:1)

Expected Behavior

The app shouldn't crash while zooming or panning while rendering 3d features

Steps to Reproduce

I'm not able to provide a code sandbox atm

Environment

• Framework version: react-map-gl@8.0.4
• Map library: maplibre-gl@5.5.0
• Browser: Chrome 135.0.7049.42
• OS: MacOs

Start by reproducing rapid zooming or panning with the terrain source https://api.maptiler.com/tiles/terrain-rgb/tiles.json, since no sandbox is provided. Read source_cache.ts around _updateRetainedTiles and update, then follow the callers in style.ts. Done means rendering terrain no longer throws the reported TypeError during navigation.
