Summoned falling block entities with Time set to 0 do not replace their corresponding block

Description

When a minecraft:falling_block entity is summoned via the /summon command and its Time value is set to 0, it does not replace the corresponding block, although the BlockState is exactly the same.

What I expected to happen

Time:0 used to replace the block it was summoned inside, if the BlockState tag of the entity was the same as the block it was inside of. This would only leave the falling block behind, giving the effect, as if the block had started to fall down.

What actually happened

The block did not disappear and did not change in any way.

How to reproduce

See attachments for details. Stand on top of a floating block of minecraft:polished_granite. Execute the following command:

/summon minecraft:falling_block ~ ~-1.0 ~ {Time:0,BlockState:{Name:"minecraft:polished_granite"}}
