In Node 4, the last statement evaluates to true, but in Node 6 it evaluates to false. Is this a bug?

F = () => {};
F.prototype = {};
Object.create(F.prototype) instanceof F;

Another user verified the behavior on their Windows system: http://stackoverflow.com/questions/38253656/instanceof-evaluates-to-true-in-node-4-but-not-node-6
