Striders can spawn in air and I can ride it through the air

A strider spawned in the air and I could ride it

What I expected to happen was...:
The strider would just fall back down

What actually happened was...:

**The strider stayed in the air and I could ride it

Steps to Reproduce:
1. Either spawn a strider with the tag NoGravity for a simulation or if you get lucky just find a flying strider IN the nether
