Issue while purchasing a theme in Safari

Hello, Envato Team

Recently our client faced an issue with purchasing a theme in Safari.
When clicking ‘Buy’ (and not the ‘Add to cart’) button, the stretched logo on dark background appears and one has to scroll to get to the login form.
Have anyone else faced such issue? And can it be solved shortly. It’s really inconvenient for the users and, possibly, influences the sales.

Best regards, DFD Team
