Possible vanilla bug? No Jellie cat spawns on any Paper 1.14 build

In my brand new 1.14 world, I’ve noticed that Jellie cats (the cat that won the community vote and was added in after the other 10 cats) don’t spawn either in initial village generation or by spawning in an established village. I commented on the vanilla bug found here:

Not sure if this is something that Paper could potentially fix but I figured I’d post this here.
