Maybe use the animationEnd event?

Just spotted this on Stack Overflow:

I actually used this approach when I was initially developing the library, but it didn't trigger reliably cross-browser, so I swapped it out for a timeout. If it's now implemented a bit more reliably in the various browsers I'm trying to support I'd definitely reconsider using it.
