Doesn't work with edge mobile

Browser version: Edge 42.0.4.4057

OS: Android 7.0;; SM-N920C Build/NRD90M

When clicking Pay button with GooglePay in https://google-pay-demo.glitch.me/, I got the error

```
(index):134 DOMException
(anonymous) @ (index):134
Promise.catch (async)
onGooglePaymentButtonClicked @ (index):132
```

And the detail inside this error is

```

You can reproduce this issue with the detail above.

I tried to find related information but cannot find useful one that would make this work in Edge mobile. What I've tried and work is switching to View desktop siteoption in mobile device. The error is gone.(Of course it works in Edge on desktop device as well)

But with View mobile site option, it doesn't work.

Expected result: It should popup dialog to login with google account and able to make payment with GooglePay.

PS: This issue also happens in my application implementation but I use google pay demo so that it can be easily check for public here.

Please advise how to make it works on Edge mobile
