I was in Creative mode, trying out the new features, and started to ride a Strider. I brought it to a vertical lava fall to try and bring it to the land above, and it slowly rose while in that lava. What I found out is that they don't fall back down when leaving the lava fall, instead just floating in the air. They can still be manipulated around but won't obey gravity.

The Strider genetates naturally with "NoGravity" in 1 (true), instead 0 (false).

This is still a bug in 20w19a
