ok, I finally understood by looking at where this is called. Then I have 2 remarks for this:
* I don't like boolean arguments, you now this, right ? :) Why can't we just call "dom.message.focus()" in toggle? This is the only place we use the argument.
* I also think we should not always focus here, we should focus only if there was the focus in the subject element first. We can use document.activeElement to check this. This can be for another bug.
