Crouch-walking speed bug

[amphyvi]

Hi, the following happens when...

1. Being fully crouched
2. Walking forward (I only use the W key to move forward in the demonstration video below)
3. Turning at just the right speed left or right using the mouse
   Jo goes flying at what appears to be the same speed as moving full-speed when standing, when also holding forward + a strafe direction.

I don't know the variables involved to reproduce this, so I've included as much as possible in case any of it is relevant. If there are any logs I can provide as well, or if there's anything I can do to help troubleshoot, please let me know.
