  <title>Test objectBoundingBox mask on element with ancestor transform</title>
  <desc>
    This test checks that the bbox calculation for an objectBoundingBox
    mask is correctly getting the bbox in the userspace of the masked
    element, and not it's bbox in an ancestor userspace or rootspace.
