Making ACR mouse scroll go back to panning an image instead of changing brush size

I have an Apple magic mouse, which lets me use its upper surface as a trackpad. In older versions of ACR, scrolling with the mouse panned the open image, as it still does in Photoshop. Starting in 2020, scrolling the mouse in ACR began changing the spot-removal brush size and adjustment brush size instead of panning the open image. I want mouse-scrolling behavior to go back to the way it was in ACR and still is in Photoshop. (Oh, sweet consistency!) Why can't Adobe give me the option in ACR to have mouse scrolling work the way I want it to? I searched and found this problem raised in forums in 2020, but as far as I can tell Adobe still hasn't provided that option.
