Breaking the bottom of a stack of snow layers breaks all snow layers above instantaneously

The bug

Breaking the supporting block of a stack of snow layers causes all supported snow layers to break at the same time.

How to reproduce

  1. Build a tower of snow layers:

    /fill ~1 ~ ~1 ~1 ~20 ~1 minecraft:snow[layers=8]
  2. Break the bottom snow layer block

Expected behavior

The breaking would spread from the bottom up gradually.

Observed behavior

All blocks break at exactly the same time.
