Description
Hi,
I've found that when using the terrain dem v1 dataset, there's a lot of elevation(?) artifacts scattered all throughout the map. I don't think this is an issue with my code as your own examples (see links down below) exhibit the same behavior, it's definitely something on the data source.
**mapbox-gl-js version**: latest
**browser**: any
### Steps to Trigger Behavior
1. Make use of the terrain dem dataset.
### Link to Demonstration
https://docs.mapbox.com/mapbox-gl-js/example/add-terrain/
https://docs.mapbox.com/mapbox-gl-js/example/hillshade/
### Expected Behavior
Continuous elevation map.
### Actual Behavior
Lots of small-ish artifacts along the elevation data.

Research direction
Reproduce the artifacts in the add-terrain and hillshade examples using the terrain DEM v1 dataset, comparing the expected continuous elevation map with the reported screenshots. Then inspect the terrain and DEM rendering path to determine whether the defect is in the dataset or rendering; done means the artifacts are explained and a verified fix or upstream data conclusion is documented.
