This is happening on Firefox 88.0.1 (current stable).
Last time I checked in with the web IDE was back in January or so. At the time, mouse-wheel scrolling moved by about three lines, just as expected. Today when I loaded up the web IDE again, mouse-wheel scrolling is moving by a full page at a time. This is extremely disorienting, due to 20 years of muscle memory around the mouse wheel.
I also tried this in the current Chrome release, 90.0.mumble. Over there, the scrolling is not quite as bad since it doesn’t move by a full page, but is jarring as well, since it moves by 8 lines instead of 3.
Given the different behavior in different browsers, I suspect there’s been a web IDE change to try to change the scroll behavior, and it’s not compatible across both browsers. Is there a way to turn that behavior off?
Scrolling by a full screen makes the web IDE basically unusable.
Thanks for any ideas!
