+      Fixes MC-119599. Vanilla places snow on a chunk while generating that chunk's features,
+      so tree parts that neighboring chunks generate into it afterwards are left without snow,
+      causing snowless patches of leaves with straight edges at chunk borders. Vanilla also
+      only places snow on the top block of each column, so lower leaf layers and the ground
+      under leaves never get snow. When enabled, snow is placed again as neighboring chunks
+      generate their features, including on lower leaf layers and the ground under leaves.
+      This changes world generation and only affects newly generated chunks.
