title: Google Web App alerts have scripts.googleusercontent.com says
body: <p>I'm building a Web App on the Google  Apps Script platform</p>
  <p>When I summon JavaScript alerts e.g.
  <code>window.alert('Thankyou for submitting your details. You will now be taken to the grammar test')</code>
  it will give me a message at the top of the alert saying <i>randomString scripts.googleusercontent.com says</i></p>
  <p><a href="https://i.stack.imgur.com/mIJdC.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/mIJdC.png" alt="screenshot" /></a></p>
  <p>This looks messy and unprofessional so I would like to get rid of it before giving to my client</p>
  <p>How can I override it?</p>
