Add scrollbars to displaystyle formulae 

Add mwe-math-element class attribute to the outermost element
holding mathematical expressions. Add a css rule that adds a
scrollbar to the element in case it's a div, which is the case
for displaystyle formulae.

Note, there will be no scroll bar if long formulae are not
explicitly marked up das displaystyle formulae.ƒ
