 * (or the default generic font family) of the first instance
 * the web font is mentioned in CSS. It switches to this font
 * immediately while loading web font, causing two changes in
 * font to occur (compared to other browsers which only change
 * font once the web font has loaded.)
 *
 * The bug has been fixed and is only happens in WebKit versions
 * below 536.11. Even though it is fixed we still have a large
 * percentage of users on older WebKit versions, mostly on mobile
 * platforms.
