Blocked form submission because the form's frame is sandboxed

When you click on a URL from a mail showed from the popup (after clicking on the Checker Plus icon in Chrome), it's impossible to submit any form on this website. There is the error "Blocked form submission because the form's frame is sandboxed".

You need to open the website in a new tab to be able to submit (but people don't know that, they just see the Submit buttons have no effects).

Is there a way to fix that or a workaround site-side?


Thanks.
