When PayPal window is closed, cannot return back to Recurly.js/PayPal page.

In the circumstance where the PayPal window is manually closed using browser controls, A message appears that states "Please wait for the PayPal transaction to finish...". The user is unable to return back to the Recurly PayPal payment page.

Solution: An option would be to add a "Go Back" button underneath the loading message that appears. Such a button could re-direct the user back to the Recurly Paypal page.
