Details

Technically, the size in Alpha channel can differ from the Y channel's one in AVIF format. But we assume they should be matched in our code.

We should handle those cases as well if it's not uncommon in the wild.

I've corrected the description as what comment 1 suggest

As mentioned in your link, the size of the primary and alpha images may differ, but specifically for AVIF, the bit-depth must be the same.

Summary: Handle AVIF file whose size, color-depth, or stride in Alpha channel differs from the Y channel's one → Handle AVIF file whose size in Alpha channel differs from the Y channel's one
