// IE8 has an odd bug with handling font icons in pseudo elements;
// it will render the icon once and not update it when something
// like text color is changed via style addition or removal.
// We have to force icon repaint by adding a style with forced empty
// pseudo element content, (x-sync-repaint) and removing it back to work
// around this issue.
// See this: https://github.com/FortAwesome/Font-Awesome/issues/954
// and this: https://github.com/twbs/bootstrap/issues/13863
