Javascript error in event handler! Event Type = element [edge.2.0.0.min.js:162]

I'm doing a little edge project (now in beta version) for my girlfriend (she hates the code), with examples of the animate() method and other functions like setInteval(), but when I run I get the following error in Chrome console:

Javascript error in event handler! Event Type = element [edge.2.0.0.min.js:162]

But this library is global for all projects, how is possible that trigger an error?

Example here:

Thanks.
