Water and lava falling_block entities are no longer visible even though they used to be

minecraft:falling_block entities which represent minecraft:water and minecraft:lava are no longer are visible, even though they used to be in prior versions; those versions had the correct behaviour, whereas current versions do not.

To reproduce:

• Run the command /summon FallingSand ~ ~ ~ {Time:1b,TileID:8} in 1.7.10

• Run the command /summon FallingSand ~ ~ ~ {Time:1b,TileID:8} in 1.8

• Run the command /summon falling_block ^ ^2 ^5 {BlockState:{Name:"minecraft:water"},Time:1b} in the latest version

Expected result: falling water would be visible.

Actual result: falling water is indeed visible in 1.7.10, however in 26.2 (the latest version as of writing) it is entirely invisible until it becomes a block proper. This is strange and unwanted behaviour.
