We have just the test with the 2k key. When we will get this fixed here an in the isoapplet repo, can you adjust also the following test line to generate the 4k key (or create another one):

https://github.com/OpenSC/OpenSC/blob/master/.github/test-isoapplet.sh#L74

It will need adjustment of the reference json file. I will try to keep an eye on that, but please remind me if I will forget:
