1.15.0.51 Breaks Ender Gateways in 1.14 saves

Went to end world to see if there were any changes in the Beta. Looked same as 1.14 but then I tried using a gateway and ended up suffocating in end stone instead of teleporting to the outer island gateway like usual. I tried going there using my oculus rift and then tried from the console too (to be sure it wasnt just an occulus issue)
