    sfusd.edu: Trying to load SFUSD School Finder sometimes fails

    Trying to load the following link often fails in Safari (and Firefox), works fine in Chrome:
    https://www.sfusd.edu/schools/enroll/discover/school-finder

    We see the following error in the JS console:
    ```
    [Error] ReferenceError: Can't find variable: google
    	(anonymous function) (js_h2tB6IRXjTJGY_6Kj6g8zvcS1bzOjvsppQOjs7XaUWs.js:12:176)
    ```

    This is caused by the google maps script being marked as async while one of the sync script
    tries to access `window.google.maps`.

    Add a quirk to ignore 'async' on scripts on sfusd.edu as a workaround while we reach out
    to the site owners.
