I want to report a bug in the layout in the review queues.
As you can see there is a scroll bar on the bottom, so it's not responsive. That's not the problem. When I scroll to the right, the left menu stays put and overlaps the scrolling part of the page like shown below:
Happens in Chrome 49.0.2623.112 on Windows XP (not supported), but not Firefox 47.0.2 on Windows XP. Also happens in IE 11.285.17134.0 on Windows 10 (supported).
