incorrect removal of parentheses in (-(--t))

[Zaitsev]

"fuse-box": "4.0.1-next.4",

in https://github.com/d3/d3-ease/blob/1e6f392ea72af6485d810e2214508a2350c64a8b/src/elastic.js#L11 they use

  return a * tpmt(-(--t)) * Math.sin((s - t) / p);

which is compiled to

   return a * math_js_1.tpmt(---t) * Math.sin((s - t) / p);

that leads to exception Uncaught SyntaxError: Invalid left-hand side expression in prefix operation
