src/functions.js was returning two properties referring to the base; since buildHTML runs
JSON.parse(JSON.stringify(tree))
to get an immutable copy, that meant we'd traverse and serialize and parse an exponentially-sized tree.Test Plan:
\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{\breve{A}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}
renders instantly; previously, it reliably timed out with even half that depth.
