wrong first slide with html picture tag about bxslider-4

[netfeld]

Simple Bugfix:

       onSliderLoad: function(){
            //bugfix https://github.com/stevenwanderski/bxslider-4/issues/1284
            //move to first slide
            let firstChild=$(this).children().first();
            let width=firstChild.width();
            $(this).css("transform","translate3d(-"+width+"px,0,0)");
        }

I had the same problem in Chrome Version 92.0.4515.131 but with tags. I applied this fix and the problem was resolved. Thanks.
