Description
**mapbox-gl-js version**:
v3.4.0
**browser**:
Chrome 125
### Steps to Trigger Behavior
1. Upload a raster file ([file used in example can be found here](https://inzenl.com/raster.tiff))
2. Add the raster source with this file to mapbox
3. Add the raster layer *with "paint"."raster-resampling" set to "nearest"*
4. Zoom in

### Expected Behavior
Mapbox should display something like this (taken from QGIS)
### Actual Behavior
It still seems to do *some* type of linear scaling

Research direction
Reproduce the behavior using the linked JSBin, the raster.tiff example, and mapbox-gl-js v3.4.0 in Chrome 125, then inspect the raster layer handling for the raster-resampling paint setting. Done means a raster layer configured with "nearest" displays nearest-neighbor sampling when zoomed in, rather than the observed linear scaling.
