image devider cutting off parallax effect ?

I am using a parallax plugin to create a simple parallax background , a simple demo can be seen HERE. Now there is this devider on the page, see below:

That's actually an absolutely positioned image inside the <main> element , now i have added an parallax effect to the container below the divider, the problem is that the divider is cutting off the parallax effect , how do i avoid that ?
