It seems to really break down when dealing with parenthesis and other kinds of punctuation that uses matching. Just from my personal testing on the linked page it got really confusing when they got to the founders section about "Frank Waldman (CEO and Co-founder), Maik Maurer (CTO and Co-founder)"

The parenthesis here, rather than showing a complete group, end up getting broken apart and stuck to whatever word they're adjacent words. "...Co Founder)"
