Summary:
Mobs with a weaving effect, when dying, can replace snow 2-8 layers.
This occurs after fixing MC-269974.
Steps to reproduce:
Create a superflat world
/fill ~40 ~ ~40 ~-40 ~ ~-40 minecraft:snow[layers=8]
Spawn a mob on the snow with 8 layers
/effect give @e minecraft:weaving
Kill the mob
Observed results:
Some 8-layer snow blocks have been replaced with cobwebs.
Expected results:
8-layer snow will not be replaced by cobwebs.

Relates to MC-261628 on the basis that replaceability is being handled incorrectly.
