Not sure what the desired behavior is here, but I assumed that calling _.clone on an object created with Object.create(null) would create a new object which does not inherit from Object.prototype.

var obj = Object.create(null);
// typeof obj.hasOwnProperty === "undefined"
var obj2 = _.clone(obj);
// typeof obj2.hasOwnProperty === "function"

Couldn't find any prior tickets, but I could have missed something.

A shallow clone won't do that as it's just _.assign({}, object) and a deep clone is loosely based on the structured cloning algorithm and doesn't attempt to clone inheritance or lack thereof .
