Didn't test it on mobile devices yet but if you are reffering to the wikiamobile skin than I fear I have bad news:

The wikia mobile skin doesn't support js & css located from the common. Beside some hacks it isn't possible to implement this script. It's about the same reason the stats script on the champion infobox won't function. You can still use the script but only when you visit the full site and so switch to the oasis skin.

I could be possible the script could contains bugs for the oasis skin. The z-index rules are still pretty poor on those area's.
