[MC-124260] An entity that gets the NoGravity tag while falling does not stop moving until 15 seconds

If you spawn an entity (that either starts floating or falling) and use the command

/data merge entity @e[type=minecraft:falling_block,limit=1] {NoGravity:1b}

the entity doesn't stop moving until some seconds, instead of that it goes more and more slowly.

Method 1:
Create a falling_block by placing a sand block, immediately after that use the command (said above)

Method 2:
Set a command block as 'Repeating' and 'Always Active,' place a dropper with something inside and give the dropper power

Makes perfect sense: gravity stops giving it more momentum, but it still has some until air resistance slows it down.

Confirmed for 1.13.1.

Command: /data merge entity @e[type=minecraft:falling_block,limit=1] {NoGravity:1b}

Agreed with tryshtar, additionally editing nbt tags during the lifetime of an entity is not supported.
