The Bug
You can see through certain transparent blocks (e.g. honey blocks, slime blocks, tinted glasses, and stained glasses) if you drop transparent items, or when someone else is holding a transparent item.

When it comes to rendering elements such as particles, block hitboxes, and other transparent objects, it appears that Mojang has to chose 1 out of 4 possible rendering bugs:
Always rendered in front of transparent blocks, even when being behind (MC-188673 for example)
Always rendering behind transparent blocks, even when being in front of (MC-161926 or MC-161879 for example)
Never being rendered behind transparent blocks (particles for example as reported in MC-188529 or MC-161899)
Transparent blocks not being rendered behind it (MC-187783 or MC-193051 for example)
Issues numbered 3 and 4 can be resolved by enabling fabulous graphics. Addressing MC-193051 might potentially reintroduce MC-165156, which could lead to a worse situation. Hence, it may be prudent to consider marking this issue as "won't fix," given that MC-165156 poses a greater problem than MC-193051.
Thank you for your report!
After consideration, the issue is being closed as Won't Fix.
Please note that this is not the same as Working as Intended, as this bug report correctly describes behavior in the game that might not be the intended or desirable behavior, but it will not be fixed right now. Sometimes, this is because the issue reported is minor and/or impossible to change without large architectural changes to the code base.
