I wouldn't say the side option has higher precedence than the anchor
option. They work together, when you specify only one of them the
other assumes its default value, when you specify neither of them then
they both assume their default values.

Looks a good addition, I have no idea when I will be able to
contribute to it (or even if it will be needed) but I can take a look
at it at least.
