If you change the mouseWheelSensitivity to say 1,000,000 (which I have it set to), it fixes the scrolling, but also makes it so that if you try to scroll in one of the tabs, it automatically goes to the top from the bottom : no way to get in the middle at all. I don't know if this is how it's meant to be but it doesn't seem like it, and I don't want to have to deal with this when servers update SO PLS FIX

also just a suggestion: make mouseWheelSensitivity have it's own Setting in the options menu because the everyday noob isn't gonna know how to go to the Minecraft folder and change something
