Building extrusion rendering bugs out when combined with 3D terrain and rasterarray

Nobody has claimed this yet.

**mapbox-gl-js version**: 3.12.0

**browser**: Safari 18.5 and Firefox 138.0.4 on MacOS 15.5

### Steps to Trigger Behavior

1. Open the demo Map via the link below
2. Pan North (up) without zooming, at least a few full screen heights
3. Observe rendering glitches and subsequent failure to render building extrusions properly (see screenshots)

### Link to Demonstration

This map style is based on the Standard basemap. We modify only the terrain exaggeration to stay on through the upper zoom levels (default behavior is to enable only in the mid-range zoom levels). Then we add our rasterarray produced with Raster MTS.

[Demonstration map](https://api.mapbox.com/styles/v1/sphericalstudio/cmb8rudah00mt01rkfwdw2b02.html?title=view&access_token=pk.eyJ1Ijoic3BoZXJpY2Fsc3R1ZGlvIiwiYSI6ImNsMXZ3cWg1bzJtZzAzZm1vZmdrd25jNXUifQ.CzQEHB0ezuWYC7YsCirOPA&zoomwheel=true&fresh=true#15.78/34.032693/-118.244514/0/64)

### Expected Behavior

Users should be able to pan around the map at high zoom levels without any visual glitches. In a [duplicated demonstration](https://api.mapbox.com/styles/v1/sphericalstudio/cmb8rudah00mt01rkfwdw2b02.html?title=view&access_token=pk.eyJ1Ijoic3BoZXJpY2Fsc3R1ZGlvIiwiYSI6ImNsMXZ3cWg1bzJtZzAzZm1vZmdrd25jNXUifQ.CzQEHB0ezuWYC7YsCirOPA&zoomwheel=true&fresh=true#15.78/34.032693/-118.244514/0/64) map, we remove the rasterarray layer and observe normal behavior.

### Actual Behavior

Panning the map at high zoom levels (~z15.5) over terrain causes the elevation in some areas of the map to eventually "drop out". In Safari only, we see a telling console error and stacktrace. Subsequently, building extrusions fail to render properly for all/most of the map until a browser refresh.

In Safari, the following error appears in the console at the onset of unexpected behavior.

```

The following networks errors were present, though they seem benign (chronological).

The GET requests for rasterarray tiles appear to be cancelled, rather than failed requests.

Start with the linked demonstration and the Safari console stack trace in mapbox-gl.js, especially _prepareDEMTextures and updateTileBinding. Compare behavior with the rasterarray layer enabled and removed while panning at high zoom over terrain. Done means the reproduction no longer produces the texSubImage2D error, elevation dropout, or persistent building-extrusion failure.
