Entities still render despite blocks being faded out

The Bug:

Entities still render despite blocks being faded out.

Slimes render through the ceiling of the building they are in when the ceiling is not rendered. I built a slime farm in a swamp and the AFK platform is way up in the sky with a tinted glass floor. The slime farm is just barely in loading distance and is not rendered, as per the attachment I've provided, but the slimes within are rendered and are able to be seen hopping around, even though there is a block in between the player and the slimes. The roof above them is top-side stone slabs. I have also attached a picture of the slime farm, and a picture of my video settings.

Steps to Reproduce:

1. Set the time to "noon" and summon a creeper fifty blocks above you by running the commands provided below.

   /time set noon

   /summon minecraft:creeper ~ ~50 ~ {NoAI:1b}

2. Navigate to your video settings and set your render distance to 2 chunks.

3. Look up at the creeper that's floating in the sky.

4. Take note as to whether or not entities still render despite blocks being faded out.

Observed Behavior:

Entities are rendered.

Expected Behavior:

Entities would not be rendered.
