Drowned have some transparent pixels within their inner body texture

The Bug:

Drowned have some transparent pixels within their inner body texture.

Throughout the drowned model, only the outer layers consist of transparent pixels to allow detail within the inner layers to be seen, however, there are some pixels within the inner body texture that are transparent and allow the inside of the model to be visible.

This could be intentional but since transparent pixels cannot be seen anywhere else throughout the model's inner layers, I've reported it to give Mojang a decision as to whether or not this is intentional.

Steps to Reproduce:

1. Summon a drowned by using the command provided below.

   /summon minecraft:drowned ~ ~ ~ {NoAI:1b,Silent:1b}

2. Look closely at the lower corner of the body texture.

3. Take note as to whether or not drowned have some transparent pixels within their inner body texture.

Observed Behavior:

There are some transparent pixels.

Expected Behavior:

There would not be any transparent pixels.
