wtf.js

$('#calendar .barIcons > .barIcon').each(function (i, icon) {
    var left;
    icon = $(icon);
    
    left = parseInt(icon.position().left, 10);
    alert(left); // increases each time
    return; // Comment this and now the alert is zero each time.
    icon.css({
        "position": "absolute"
    });
});

(The CSS and structure of the page shouldn't even make a difference - I just can't see how the position().left could POSSIBLY be affected by the position: absolute; it's value must have been resolved BEFORE the position absolute is applied.)

@getify yeah I know console.log can be async - didn't think alert could. But even then, it is actually setting the values to zero too, even without the alert.
