I strongly object to this definition.  The concept of "user action" is 
very UA-specific, and should in my opinion be up to the UA.

For example, I believe as a UA author I should have the option of 
treating a click on "opacity:0.00001" content as not a user action.... 
I fully expect UAs to end up implementing such heuristics as more and 
more sites try to use hacks like that to work around UA popup blocking; 
if we put even more important things than popups in the same bucket, 
then there will be even more incentive for both the hacks and the 
improved heuristics.

I agree that sharing this definition across specifications is a really 
good idea, because I expect it to be hard to define this sanely.
