Slime spawning ignores height available

Large slimes spawn in slime chunks in areas that are 2.0 blocks tall, and even in area that are 1.8125 blocks tall (2 block space -  trapdoor on the underside of the ceiling block). The large slimes also do not suffocate when they spawn.

Noticed when building a hostile mob system on my bedrock realm. Screenshot of one stuck jumping in place.

Tested on offline worlds, the realm, Xbox one and Android - all running 1.14.1.

I have observed this too on Win 10 with swamp slimes in a 2 block high space. Big Daddy could not move that did not stop him showing up to the party.

Affects 1.16.221 Hotfix

The reason this occurs is the same as for magma cubes: the spawning function relies on data from the components section of the entity json, but the collision box for each size slime is given only in the component group for that size.

The bug can be fixed by copying the large slime collsion_box component into the main "components" section of the slime.json.

"minecraft:collision_box": {
        "width": 2.08,
        "height": 2.08
      },
