Many things are not rendered through translucent allay or vex texture regions

The bug

When trying to view certain game objects through translucent regions of an allay or vex, they just don't render. Examples include but are almost certaintly not limited to:

• dropped translucent items
• placed translucent blocks
• clouds
• beacon beams

How to reproduce

Create a setup where any one of these things can be seen through these areas of the allay/vex texture. The follow commands will be useful:
/summon minecraft:allay ~ ~1 ~

{NoAI:1b}

/summon minecraft:vex ~ ~1 ~

{NoAI:1b}

Expected results

the thing to be visible

Actual results

It is not.
