The Bug:

Entities sink or fall through snow when it accumulates while the "snowAccumulationHeight" gamerule is set to any value greater than 1.

This is problematic because as a result of this behavior occurring, entities can get stuck in blocks thus creating a noticeable inconvenience. Given the triaging/fixing of reports such as MC-252730, MC-251030, and MC-250034, I'm inclined to believe that this isn't intentional.

Steps to Reproduce:

• Enter a biome where its precipitation is snow, for example, a snowy beach.
• Summon a platform of blocks with some snow on top of them.

• /fill ~1 ~ ~1 ~7 ~ ~7 minecraft:polished_andesite

• /fill ~1 ~1 ~1 ~7 ~1 ~7 minecraft:snow[layers=4]

• Place armor stands on top of each block of snow.
• Set the "snowAccumulationHeight" gamerule to "8" and the weather to "rain".

• /gamerule snowAccumulationHeight 8

• /weather rain

• Watch the armor stands closely for around a minute as the snow beneath them accumulates.
• Take note as to whether or not entities sink or fall through snow when it accumulates while the "snowAccumulationHeight" gamerule is set to any value greater than 1.

Observed Behavior:

Entities sink or fall through snow.

Expected Behavior:

Entities would not sink or fall through snow.
