Featherlight is a very lightweight jQuery lightbox plugin. It's simple yet flexible and easy to use. Featherlight has minimal css and uses no inline styles, everything is name-spaced, it's completely customizable via config object and offers image, ajax and iframe support out of the box. Featherlights small footprint weights about 4kB – in total.
I'm sorry, I don't see how that would be a Featherlight bug. If you remove the library from your page you will still have the exact same issue!
Good luck
