 * is not null before appending it to the style string. Otherwise the css parser throws
 * an error because the string 'null 'is appended to the css.
 *
 * erlyberly has not upgraded to the latest fontawesomefx because the Icon class now
 * inherits from Text and not Label so tooltips cannot be set.
