[MathML] Use 'safe' center positioning for display=block

Previously we'd just center the contents for is_block_math. Doing this
would lead to however lead to un-reachable content if the \<math> element
also had overflow: scroll placed upon it.

Use 'safe' center positioning instead - that is center, but don't allow
the content to be place before the content edge.
