## Description
Chrome 53 doesn't like the minified output. Specifically, it throws
`Uncaught SyntaxError: Unexpected token (` on the ternary in the
minified version of `normalizeListenArgs()`
e78bcc7b2d/src/js/mixins/evented.js (L165-L195)
Line breaks added for clarify
```js
Tt = (e, t, s) => {
var i = t.length < 3 || t[0] === e || t[0] === e.eventBusEl_;
let r, n, a;
return i ? (r = e.eventBusEl_, 3 <= t.length && t.shift(), [n, a] = t) : [r, n, a] = t, ft(r, e, s), yt(n, e, s), bt(a, e, s), a = _(e, a), {
isTargetingSelf: I,
target: r,
type: n,
listener: a
}
},
```
Chrome would be happy with this if `[r, n, a] = t` were `([r, n, a] =
t)`.
## Specific Changes proposed
Refactor `normalizeListenArgs()` slightly to use multiple statements to
coerce uglify-js to include parentheses.
Also updates uglify-js, but that in itself isn't the fix.
Fixes#8783
