Pjax and scrollTo

I’ve been using the Pjax widget and trying to get the ‘scrollTo’ attribute set to not scroll on update. I can’t get it working and either it’s a bug or I’m missing something. The Pjax widget uses the Html::tag method to render the attributes. This method will explicitly not render the attribute if it is false. However you can’t set the ‘scrollTo’ attribute to 0, since this means that you scroll to the top of the page. I can solve my problem by setting the Pjax default attribute $.pjax.defaults.scrollTo=false, but I’d still like to know if there is any way I can just use the ‘scrollTo’ attribute.
