title: Favicon not displaying in most browsers and shows odd src path. React + Express Server
body: <p>I am serving a react application on an express server deployed to Heroku. Locally I can easily see my favicon. When deployed it is not showing up.  I am getting a status 200 on the file but when I click preview it is showing this as the src:<a href="https://reactportfoliodh.herokuapp.com//favicon.ico" rel="nofollow noreferrer">https://reactportfoliodh.herokuapp.com//favicon.ico</a>.  For the life of me I cannot figure out why it is showing two forward slashes.  To make matters worse another person says they CAN see it. I have already tried emptying my cache and tried multiple computers...Anyone?</p>
