Description
mapbox-gl-js 2.8.2
browser: chrome/firefox
### Steps to Trigger Behavior
Add an image layer
Draw the image extent as a geojson polygon
The extents do not match
### Link to Demonstration
https://jsbin.com/juturac/edit?html,output
Enable cross origin requests as it links to an external image
### Expected Behavior
I would expect the polygon and the image extent to match
### Actual Behavior
There is a minor offset
### QGIS Behavior
This is the same raster data loaded in QGIS
Here the extent is the same as the rendered geojson polygon. So it looks like there is some offset when rendering images.
I have submitted this issue before #9396 and it was marked as a duplicate of #9158.
#9158 is fixed now but this issue still occurs.

Research direction
Start by reproducing the mismatch in the linked JSBin with Chrome or Firefox: add the image layer and compare its rendered extent with the GeoJSON polygon. Use the supplied screenshots and QGIS comparison as the reference. Done means the image and polygon extents align, and the behavior remains correct after the fix for #9158.
