I have been trying to embed a website into a private page, and have tried out the "embed" and "iframe" tags, but as soon as I update the changes it redirects to the embedded site. I read more about the subject and found out that if I used the sandbox option, then I could prevent that from happening:

<iframe src="/" width="100%" height="650" name="disable-x-frame-options" sandbox="allow-forms allow-popups allow-pointer-lock allow-same-origin allow-scripts"></iframe>

Even though the page itself is stable and the iframe is working perfectly, the editor keeps redirecting, too quick for me to make any further changes to it. Is there any way of preventing the page's editor from doing this?
