/**
 * @assertion final paddingEdge
 * Access the dimensions and position of this element's content + padding 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.
 * @issue 43294
