Falling Blocks Named Dinnerbone Aren't Upsidedown

I used the commands
{{/summon minecraft:falling_block ~ ~ ~ {CustomName:"

{\"text\":\"Dinnerbone\"}

",CustomNameVisible:1b,BlockState:{Name:"minecraft:dragon_egg"},Time:1}}}

and
{{/summon minecraft:sheep ~ ~0.1 ~ {CustomName:"

{\"text\":\"Dinnerbone\"}

",CustomNameVisible:1b,NoAI:1b,Silent:1b}}}

{{to summon the }}entities
