Modal within a Modal in Ruby on Rails?

Question

I have a Ruby on Rails app with Livepipe widgets - http://livepipe.net/ - and everything has been going great, until the client asked for a modal ontop of another modal.

Swapping between modals isn't a problem, but they'd like to see one modal behind the other.

I can tell that the tag with the id="control_overlay" is the issue - both modals are trying to share it, but I'm not sure how to solve this without ripping apart or duplicating a lot of the the highly tuned livepipe code.

Is there an easy way around this that I'm not seeing? Is there a better prototype compatible JavaScript library I could be using? I'd appreciate any help.
