Custom Slider Widget Disappears everytime Chrome or Safari Quits

Working off the Aquatouch preset, I was able to get the youtube scrubber to work on both Safari and Chrome but it never persists.

Every time I get it so that it works completely perfectly and everything is in the right order, it doesn't last when the browser closes. If I change the tiniest thing for the slider (size, display order, padding,etc.) it reappears and everything works fine again but only until i close the browser again.

Any idea what I'm doing wrong?
