End portal infinite teleport loop

Sprint Swimming to fit into the one block gap of the entry portal results in getting stuck inside the portal and teleporting back and forth endlessly. Also it drains hunger for some reason ?

Using an Ender Pearl or breaking the bedrock and dropping directly into the portal results in getting stuck with no movement or world render at the coordinates of the entry portal

(See screenshots to understand the setup. Basically we used swimming to traverse the portals without using an ender pearl)
