| * @description This test checks if offsetParent is always null when accessed |
| * from the HTML <body> and from elements with CSS property position:fixed. |
| * To ensure values match layout, this test also checks offsetTop and |
| * offsetLeft. |
| * In addition to the HTML <body>, two elements with CSS property |
| * position:fixed are tested: One within the body, and one within an element |
| * with CSS property position:absolute. |
| * Finally, a static- and relative-positioned element are tested for sanity |
| * and spec adherence. |
