Put the summary of the bug you're having here

What I expected to happen was...:
Dropping Items in front of placed Honey blocks would keep the honey blocks semi-transparent, while rendering dropped items in front of them

What actually happened was...:

Doing so makes honey blocks completely transparent

 Also works with Slime blocks

Steps to Reproduce:

1. Create wall of honey blocks, 1 layer deep
2. Place a marker behind honey blocks, you should not be able to see them very well
3. spam the "q" key and drop items in front of your face,

4. you should be able to see the marker behind the honey block structure much more clearly while the items are in front of your face
