Test passes if you see two squares with differently colored borders:

• Both squares should be inside a vertical black-bordered rectangle that lacks the bottom border
• The first (blue) square should have an irregular width purple border that overlaps the whole width of the left black border of the containing rectangle
• The second (green) square should have an irregular light green border: the top edge of the border should be invisible (zero width) while the bottom border should be thin and overlap the whole width of the bottom black border of the containing rectangle
