| * @assertion final marginEdge |
| * Access the dimensions and position of this element's content + padding + |
| * border + margin box. |
| * This returns a rectangle with the dimenions actually available for content |
| * in this element, in pixels, regardless of this element's box-sizing |
| * property. Unlike getBoundingClientRect, the dimensions of this rectangle |
| * will return the same numerical height if the element is hidden or not. |
| * @description Checks that if element is hidden it does not affect dimensions |
| * of the rectangle. |
