True, I suppose test scenarios can't hurt - but the fact is that 
mouseRelease (outside button) is a recognized convention. Virtually 
every professional application on all computer platforms function with 
this behavior. Try it on any button you have in whatever you are viewing 
this email in.

Test if you like, but I wouldn't spend too much time or money on the 
subject (I imagine someone already did - 15 years ago)...  :)
