Closely relates to MC-193051. May also relate to and/or clone MC-35920 and/or MC-9553. Discovered while testing MC-248703.

The bug

If a minecart is summoned which displays a translucent block inside it, any other translucent game objects positioned behind that translucent block will not render. This only affects the Fast and Fancy graphics settings.

How to reproduce

1. Summon a minecart containing red stained glass:

   /summon minecraft:minecart ~ ~ ~ {CustomDisplayTile:1b,DisplayState:{Name:"minecraft:red_stained_glass"},DisplayOffset:16}

2. Place something translucent nearby
3. Look at this translucent thing from behind the minecart's glass

Expected results

The translucent thing would still be visible from behind the minecart.

Actual results

That is only the case for Fabulous! graphics - on Fast and Fancy graphics the object is occluded by the glass.
