Freecam in minecart dismounts when flying down on servers

[collin-b1]

Description of the issue

When you are riding a minecart (and presumably other mountable items/mobs), flying down in freecam by holding the crouch key causes the player to dismount (only happens on servers)

Expected behavior

The player should be able to control the freecam without dismounting the minecart on servers

Steps to reproduce

1. Go to a multiplayer server
2. Enter a minecart
3. Go into freecam
4. Fly down by holding the crouch key (shift by default)
