Horizontal scroll is backwards (shift-scroll wheel)

If I hold down shift and use the scroll wheel on any desktop window, scrolling up moves to the left, scrolling down moves to the right. It's backwards in Roll20. If this is somehow to protect some legacy system, can you at least provide a setting to reverse the horizontal scroll direction?

Please... Why did Roll20 decide that horizontal scroll should be backwards from all other systems? Why do I let you treat me like this?

I can verify that the difference is as Mike deBoston reports. I get the opposite left-right behavior between Roll20 and say, scrolling around a large image in a Chrome window. Shift-Scroll Up moves the background image to the right (sUR) in the general browser experience, but to the left in Roll20 (sUL). I almost never use the scroll wheel to move the window in Roll20, so hadn't noticed. In fact, I do it rarely enough anywhere that I have no muscle memory to overcome. FWIW, the scrolling direction feels very normal using a trackpad to drag.
