[MC-48107] FallingSand Bug (riding a villager)

When you summon a FallingSand entity which rides a villager (time of FallingSand is not 0), the block of sand will fall down after about 10 seconds, for example:

/summon FallingSand ~ ~4 ~ {DropItem:0,Time:1,Riding:{id:Villager,CustomName:Spieler1,ActiveEffects:[{Id:14,Amplifier:2,Duration:1000000,Ambient:1},{Id:2,Amplifier:50,Duration:1000000,Ambient:1},{Id:8,Amplifier:200,Duration:1000000,Ambient:1},{Id:11,Amplifier:50,Duration:1000000,Ambient:1}]}}

Yes also happens with Time:1
