The "Annotations" area, if it contains more items than can be shown at once, scrolls vertically for me in Chrome and Safari but not in Firefox. Firefox does not display a scroll bar or scroll with a scroll event from my mouse.
Interesting, I was able to replicate the bug. It looks like the height is going past the bottom of the page. I think it might be a flex-box issue, will check it out!
