The redirect modal keeps showing up when customer clicks the back button in Safari

[leonardola]

Describe the bug

When a customer goes to WooPay and then clicks the browser back button on safari the redirecting modal keeps showing up.

Fixing this might be tricky because apparently the javascript code does not run when clicking the back button in safari. Maybe we'll need to close the modal just before the redirect actually starts.

To Reproduce

• Add a product to your cart and checkout using WooPay
• When you get to the WooPay checkout click the Browser back button
• The redirect modal will keep showing up in the merchant site

Actual behavior
