Apply anchor-center to base style

ApplyAnchorData() was applied once for style resolution, and only after
the base style was cloned. When the base style was used for computing
fallback positions we would use an undefined anchor-center for
alignment.

Make sure we compute the anchor-center position before storing the base
style.
