A scroll sensitivity of 1-10 behaves the same when switching hotbar slots using the middle mouse wheel

When I was playing survival, I noticed that my hotbar scrolling was very slow. I turned the scrolling sensitivity up to 10, and the scrolling was the same speed. I even tried numbers in between 1 and 10, but they didn't work either. The scrolling sensitivity is only affected when it's under 1.

What I expected to happen was...:
the hotbar scrolling to be way faster, just like when the mouse sensitivity is high.

What actually happened was...:
the speed was the same as it was before.
Steps to Reproduce:

1. esc -> Options -> Controls -> Mouse settings -> Scroll Sensitivity
2. Set it to 1.00.
3. Scroll through each of the hotbar slots, 1 notch at a time.
4. Set the scroll sensitivity to 10.00 and repeat step 3.
