 * by default but content can't be shown underneath them for for static
 * elements.

 * Note: This will return `0` on Mac OS with the default "Only show scrollbars
 * when scrolling" which is to be expected. These scrollbars overlay the content
 * and actually don't take up height/width real estate.
