1366x768, so I just decided to view a page at half my screen width. First I notice the left margin is there wasting a bit of space. But okay, whatever. But overflow is hidden. So the page didn't fit in my window but there was no scrollbar (which also means I couldn't offset the margin like I used to by scrolling slightly right).

Fix that.
