Cannot use v5/Smart Payment Buttons with popup bridge

Description

We’re trying to setup the smart payment buttons together with the braintree PopupBridge and we’re getting an empty returnUrl back instead of the native redirectUri from reconstructReturnUrl (redirects.js). This is because if(!url) below is true (url is '').

This causes our popup bridge to never be called with a deep link but instead the page will just reload itself inside the “popup” (safari window).

Isn’t the usage of the smart payment buttons together with the popup bridge supported?

(Braintree checkout is not an option since we don’t control the back end, and checkout.js v4 doesn’t seem to work for us either since the callback from the popup bridge doesn’t provide the order ID back. We need it though for the authorization.)

Steps to reproduce

1. Setup the popup-bridge-ios and load the smart payment buttons in the corresponding webview
2. Run the application and click the PayPal button
3. Enter credentials and checkout
4. Observe how the page reloads the last checkout step instead of returning to the popup bridge
