Inversion of image outside of BBOX in STAC Browser

[Ruphai]

Issue

I currently have an collection uploaded to STAC Browser FastAPI here. The collection and corresponding items have been validated and show to work correctly and even loads into an xArray object using odc-stac. However, on STAC Browser, the visualization of the image is inverted outside of the bounding box, see sample images below. What do you suggest might be the cause of this inversion?

What the Original Collection looks like:

Possible cause

It seems this might be due to an inversion of the coords in the transformation matrix (especially in the Y axis)

@m-mohr It might be related to this: geotiffjs/geotiff.js#337

[m-mohr]

Yes, might be. The first check should be whether the latest version of geotiff.js is used. I don't have th capacity to check this right now, but the fix must either be made in stac-layer or in geotiff.js anyway. Did you check whether this works correctly with ol-stac?
