That's what it does do, but that doesn't change the fact that the
signal handler gets called with the event object.

That is what it does.

I don't understand what you're trying to say here, but the docs are
correct...

That's because your code is still wrong. You're *calling* the show
and hide functions during the connect! I didn't see that the first
time because it wrapped to the next line. Don't do that.
This is your code:
show = function(e) {
setElementClass(e, 'popup');
}
connect('source_1', 'onmouseover', show('source_popup_1'));
This is what your code does:
setElementClass('source_popup_1', 'popup');
connect('source_1', 'onmouseover', undefined);
This is the code you want:
var show_popup = function (element, e) {
e.stop();
setElementClass(element, 'popup');
};
connect('source_1', 'onmouseover',
partial(show_popup, 'source_popup_1'));
