Hi! I’m assuming that you are using a 3rd party script for this.
The idea is not to place this script inside <head> area from: Website settings → SEO / Meta → Meta tags or Code → HTML, … because is executed in the Editor (as mentioned here).
One suggestion is to place the 3rd party script at the bottom of your page (within an HTML element as a <script> tag) inside the footer or any reference that is used across the site.
This way it will no longer be executed in the Editor.
Hope this helps!
