The sample image here fails the ComplianceWarden because items 2 & 3 don't have an ispe associated with them. However, these items are of type 'mime' and 'uri '. They're not images so they don't have a width or height.
This usually isn't an issue because most mime items don't have properties associated with them. However, the mime & uri items in the image above do in fact have at least 1 property associated with them. Looking in heif.cpp, the rule is only checked for items that have a property associated with them.
Is the file actually compliant? Are mime items considered to be "image items"?
