In the HTML file demo-youtube-iframe-bg-reveal.js.html, there are two videos in the background. When you use the navigation (keyboard shortcuts or arrows) and go to the last slide with the second video (U1 Görlitzer Bahnhof), after this started playing, going back will show the title image of the previous video (U8 Kottbusser Tor).

I can reproduce this in Firefox and Chromium.
