    LP#1831786: add demo of cross-tab communications
    
    This adds to the Angular sandbox page a demo of implementing
    cross-tab communications using BroadcastChannel. To quote the
    instructions added by this patch:
    
    "To test, open this sandbox in a second browser tab.
    Enter something in the input box below, then switch to the other tab
    and click anywhere on the page. You should see the message that you
    sent to the other browser tab."
