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.
