In Firefox 157.0.1, the right border of the image moves by a pixel or two when I press "hold for lossless" while viewing the AVIF. I think it's the lossy AVIF that's a bit too small.

That's what I'm talking about. JXL support landed in 158.

		But why does missing JXL support make the AVIF too small? It ends one pixel before the gray background.
