If open chatbox in some VRCStation, "Gounded" turn to false and VelocityY start to increase.

I confirmed this issue occur in movable VRCStation (in https://vrchat.com/home/world/wrld_e055f1a3-6fcb-4d19-9945-f0a1c92cc19b), VRCStation in Avatar, and hight changable VRCStation.

VRCStation in "VRChat Home" does not occur this issue.

This issue does not directly affect to avatar pose (normaly , avatar pose is controled by Sitting layer or VRCStation's Animator), but it has occur unintentionally tracking control setting by some layer, and unintentionally tracking causes strange pose.
