Fishtraps have z-fighting and broken transparency

[Henrykado]

(first clip is in 4.2.1, and second clip is in 4.3)

The fishtraps are rendered properly in 4.2.0 but ever since 4.2.1, they constantly have z-fighting, and in 4.3 they also have a transparency issue, with the transparent pixels being rendered as solid black in the oak fishtrap model, and as solid white in every other fishtrap variant.
The fishtraps in 4.2.0- did also have z-fighting as mentioned in #336 though there it seemingly only happened in a few specific scenarios.
