Fixes #545

The original logic for this method found the position with the least amount of overflow in a single direction, but for the optimal UX it needs to consider how much total surface area of the popover is being clipped, and choose the position where as much of the popover is visible as possible.

popover_position

… amount of visible surface area of the popover.
