Rendering glitch when looking at slimes through slime blocks

In an attempt to recreate MC-305968 in Bedrock, which is only affected in Java, I came across this weird rendering glitch.

To recreate:

1. Summon a slime or find one that naturally spawns

2. Place down some slime blocks and look at the slimes through them

Expected result: Slimes should render like any other mob, block, or player.

Actual result: Slimes are rendered with the same lighting when looking through a slime block in every angle. However, the mouth and eyes of the slime are not shown through the slime block, like any other mob, block, or player. The slime is also rendered with single layer surfaces through slime blocks, compared to its regular see-through parts.

See the attached videos.
