Holding sprint and flying straight into a wall will repeatedly toggle the sprint FOV

Holding sprint into a flat wall while flying in creative will repeatedly and rapidly increase and decrease the FOV. 

Trying to do this at an angle will act as expected

Trying this on a corner will toggle it twice - first an increase and then an immediate decrease.

I found MCPE-143877, which sounds like the same issue.

I didn't see it reported for Java by anyone else yet.
