It may be an emulator bug then? Try turning off dynarec, it'll be slow but might help on corner cases. It could also be a weird image? DC only reads the big endian TOC. But yeah it's weird. Found my proof of concept: https://pastebin.com/kqMNEwXg It works on track03 of a 5+ track game. You should use dummy track01 and 02, convert the last track to iso yourself, and edit the .gdi file manually so the data tracks are in 2048 mode. It might help you until I finish adding gdishrink to GDItools.
