Iterator.prototype.drop.call({
next() { return { done: true } },
return() { this.closed = true }
}, NaN)
Returns TypeError (Iterator result interface is not an object), expected RangeError (Iterator.prototype.drop argument must not be NaN).
https://tc39.es/ecma262/#sec-iteratorclose - exit on step 5, not 7.
