We have an application that has an Iframe inside the main page. When the application launches it access the "abc.com" domain and creates a cookie name with "abc_cookie". Then the browser address bar changed and redirects to the "pqr.com" and loads an iframe inside the main page. When the iframe src was set to "abc.com", above abc_cookie was not sent with an HTTP request. But it was sent with safari 12. I added `SameSite=None` for the cookie but no success. How can I make this work in Safari 13 as well?
