so i just find out every input field that is inside iframe (in my case: stripe's cc number, expiry date, and cvc input fields) doesn't show virtual keyboard when it's focused. how to replicate this isssue in desktop is by using chrome extension virtual keyboard. in my case, it's in occulus VR device.
