Float layer should ignore offsets from ancestor inline layers under containing block

Float layer should ignore offsets from ancestor inline layers under containing block

- When calculating layer location, we should traverse containers
  instead of parents, because containers instead of parents affect
  locations of children. This ensures we get correct location for
  floating layer.

- When calculating layer offset in an ancestor, for a float layer,
  we should skip inline ancestors below the containing block.
