E.g. when mousing over the team in the statbox.

The reason this happens is because I wasn't enough of a CSS guru to make the tooltip span appear dynamically to the left/right/up/down of the moused-over parent element, depending on whether said element is near the right/left/bottom/top edge of the viewport. Or maybe more properly: force the tooltip span's respective edges never to cross the viewport boundaries. If someone knows how to do that, please fix! 💖
