Test max functionality
Test the max properties to see if an image is returned which is outside of the allowed bounds:
https://iiif.io/api/image/3.0/#52-technical-properties
This would be an optional test and wouldn't necessarily use the test image.
This issue was created over 3 years ago. It seems that Mirador 3.0 now uses the "max" syntax rather than full, even when communicating with a IIIF 2.0 compliant image server. Bumping this test for "max" syntax up in priority and releasing an updated version of the validator here: https://iiif.io/api/image/validator would be most helpful as "max" is clearly part of the last 2.x specification.
For info I think this is a bug in Openseadragon bug report which has been fixed in OSD 3.0.0. I believe Mirador is currently using 2.4.2.
Thanks, sounds like a new Mirador bug report needs to be filed - I didn't find any existing tickets about this with M3 although it would seem to suggest that M3 won't work with image servers that don't support the "max" parameter.
