Description
**mapbox-gl-js version**: 2.6.1
**browser**: Chrome v 97.0.4692.99
### Steps to Trigger Behavior
add WMTS layer to map as "raster" (using NOAA imagery in example)
### Link to Demonstration
https://codepen.io/sanidhya-pratap-singh/pen/JjOKpqV
### Expected Behavior
All tiles should be rendered
### Actual Behavior
All tiles are not rendered correctly. Tiles are missing altogether or showing old image from lower zoom level. Constant error in browser console
`Error: Could not load image because of The source image could not be decoded.. Please make sure to use a supported image type such as PNG or JPEG. Note that SVGs are not supported.`

Research direction
Start with the linked CodePen and reproduce the NOAA WMTS raster layer in Chrome, using the browser console to confirm the image-decoding error and the missing or stale tiles. Trace the WMTS raster tile-loading path from that configuration; done means all expected tiles render correctly without decode errors or lower-zoom fallbacks.
