To be more clear, it seems they've disabled the native browser scrolling via javascript. I have wrist strain issues so I have a programmable keyboard. I don't use a mouse to scroll and click, I use a layer on my keyboard. I don't map the arrow keys or page up/page down because they generally aren't useful. I literally have to change my setup to scroll on the page. I imagine there are others in need of even more specialized equipment than mine that is broken by this implementation. I have yet to find a good reason when developing a webpage to reimplement scroll. Certainly not for a fancy progress bar which is presumably the reason this was done. This is a legitimate accessibility concern.
