Manage browser back from Paypal payments

[gionatan]

Hi,

checking the behaviour clicking back button on the browser button (instead of the cancel link) Mall seems blocked in the ajax call with the loading wheel.

Comparing with other e-commerce software I know maybe having a dedicated endpoint to jump to PayPal instead using ajax helps to avoid this issue.
Do you have any consideration about that or workaround to avoid to block the user experience?
