Sorry, it'a a Active Admin javascript bug.

@xcopy I just started seeing a similar issue today. Can you link to the AA issue here? (I know it's been a while but I'm hoping you'll remember what it was)

[betesh]

Found it: https://github.com/activeadmin/activeadmin/issues/2960

Thanks, helped me pinpoint the same problem in another JS library, though it seems I'm not the first to spot it: https://github.com/stevenwanderski/bxslider-4/pull/45/files
