User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:95.0) Gecko/20100101 Firefox/95.0

Steps to reproduce:

Scroll a page where one sticky (top 0px) image overlaps another - e.g the black background model image of https://kport.co.uk/. The effect is most visible on dark mode systems, especially when resizing the window width.

Screen recording attached.

Actual results:

There is a 1 or 2px top edge where the underlying sticky image is showing through.

Expected results:

No transparent edge. I've checked that there is no issue in Chrome 96 or Safari 15.1 using macOS Monterey 12.0.1
