Remove existing iframes - fixes v5.5 issues

[vallme2003]

Changes :

(1) Removed existing iframes: Before creating a new iframe, the script checks for and removes any existing iframes.

(2) Ensured single video element: The script removes existing video elements before creating new ones to prevent overlapping audio.

Sometimes it works, sometimes it doesn't

Thanks for checking. I am able to see it working with Chrome v125 on mac and with existing adblockers disabled. If there is a certain OS + browser combination where you see the intermittent behavior, plz add it here to check. Thanks!
