Remove the anchor.strategy option (#3120)

* remove the `strategy` options, use "absolute" by default

Right now there is no good reason to expose the strategy, because the
default is good performance wise, and using `absolute` is fine because
we are portalled so there is no parent relative container to worry
about.

* update changelog
