The spec (https://wicg.github.io/cookie-store/#set-a-cookie) says that if set is called with a path passed in, and the path does not start with a "/", then we should return a failure. This implies that passing in "" should cause a failure.

However, Chrome does not return failure here, but rather fills in the path itself and sets the cookie.

Which is correct? Returning a failure or filling in the path automatically if an empty string is passed in? Thank you!
