Browser back action does not work in Firefox when PayPal Plus iframe is rendered in page of react app
I integrated PayPal Plus into my react app as described at the link below.
Now the Problem is that clicking the "back" button on the page where the PayPal Plus iframe is inserted, doesn't work. Instead of navigating back in browsing history, this one whole page is reloaded in the iframe itself.
This behavior doesn't occur in other browsers.
I already consulted PayPal Tech Support for the issue and they proposed to ask the mozilla community.
The detailed description, including the steps to reproduce the issue, is here at stack overflow: https://stackoverflow.com/questions/64137998/browser-back-action-does-not-work-in-firefox-when-paypal-plus-iframe-is-rendered
Thank You in advance.
