/* SOLUTION */
/* The pseudo element has the same content and hover style, so it pre-sets the width of the element and visibility: hidden hides the pseudo element from actual view. */
a::before {
    display: block;
    content: attr(title);
    font-weight: bold;
    height: 0;
    overflow: hidden;
    visibility: hidden;
