[#7956] - Authentication Error in Safari when Using Visualize.js or Iframes to Embed Dashboards, Reports.

I am getting Authentication Error in Safari when Using Visualize.js or Iframes to Embed Dashboards, Reports into my web application. It is working perfectly fine with latest versions of Chrome , Firefox.

Currently Iam using basic type of authentication for visulaize.js i.e. like below

visualize.config({

auth: {
name: "username",
password: "password"
}
});

Also tried using Iframes and sending username, password as query params in the URL but Same Authentication Error pops up.
