Escape class names

[jhtvarma]

When an element has class names starting with number, the Element.matches is failing to identify the right element.

Ex: div.classA.2f683ff1c2173060crd67792e542ss17

Expected: Should identify element with classA and 2f683ff1c2173060crd67792e542ss17 as classes Actual: Element.matches throws Error as it is invalid id

@Georgegriff Let me know your thoughts on this
