There is a horizontal and a vertical scrollbar outside of the area that should actually be scrollable. They clearly shouldn't be there and making it a bit hard to use the modal.

What build was this in? Scott, I think you were adjusting some of the layouts to avoid clipping, do you have an existing bug on fixing this?

Looks like we had bug 1385813 for edit dialog only.

Just checked again with build ID 20170816100153, and it seems to be partly fixed. I now get only a horizontal scrollbar, which is invisible in macOS until you actually try scrolling to the left. New image attached. (!) Actually, had a second look and resized the window to the smallest possible size (which only changed it by 1-2 pixel in height) and got both scrollbars back.

I think it's caused by changes in preferences stylesheets. The layout in edit address dialog is affected too (filed bug 1391148). Will look into this after I finish working on credit card preferences. Thanks for filing this bug.
