And to be more precise:

1)  Gecko has supported transitions on pseudo-elements since Firefox 4 
(March 2011) and animations on pseudo-elements since Firefox 5 (June 2011).

2)  I have seen pages that do a -webkit-transition on an element but do 
the corresponding unprefixed transition and -moz-transition on the 
pseudo-element on the assumption that unprefixed implementations support 
the pseudo-element bit and given the data point that Gecko does support 
it.  These pages are not expecting an event on the pseudo-element and 
would be likely to behave incorrectly if they do get an event for that 

I believe we should use a different event name for the pseudo-element 
transitions so that web pages don't get unexpected events suddenly 
popping up.
