Which I can only answer with the results of my testing, 
either in the past or in the future.

[btw: Since I often use this method, my tests make me trust the method to 
be sound on the browser js-engines I tested, but not on say Iphone, since i 
am a Chrome and Android person with limited resources.]

Gene, that is not the way the javascript universe works.

If you want to be sure of the effect, you test it,
never trust the specs to be final.

The specs only tell you how it was ment to work.

So in fact you were [unknowingly perhaps] asking me to test it for you.
