3D Secure cancel: error different (lacking details) for `confirmPayment` on iOS

[benomatis]

When cancelling a 3D secure authentication I get the following errro object back from confirmPayment...

on Android:
{"code": "Failed", "message": "The provided PaymentMethod has failed authentication. You can provide payment_method_data or a new PaymentMethod to attempt to fulfill this PaymentIntent again."}

on iOS:
{"code": "Canceled", "message": ""}

I'm using the exact same code for both. Any reason there is such a huge difference? Is this a bug or expected for some reason?
