Strider begins to float when hit by a zoglin while the player is riding the Strider.

What I expected to happen was:

That I'll ride the strider and it'll not float

What actually happened was:

The strider started to float if it was attack by a Zoglin.

Steps to Reproduce:
1. Spawn a Zoglin and a Strider
2. Put a saddle on the Strider then let the Zoglin attack it
3. The floating it'll increase if the zoglin keeps attack the Strider.
