Is it possible to reset the cursor to the center of the screen when unlocking?

🐛 Resetting the cursor to the center of the screen when disabling Mouse Look isn't possible at this moment due to a bug on Blizzard's end introduced in patch 10.2.
Until they fix it, that feature will remain disabled to avoid the intense motion sickness it causes.
Here's a more in-depth explanation of what's going on:

Somewhere in patch 10.2, Blizzard broke something with the interaction between CursorFreelookCentering and CursorStickyCentering - the CVars that move the cursor to the center of the screen after locking and keep it there when unlocking - which is causing the camera to jolt the equivalent vector to the centered cursor position from where your cursor was before locking in. The issue makes it impossible to release the cursor at the position of the crosshair as it causes intense motion sickness due to the erratic camera behavior.
