Vertical scroll with fixed position header

[NikkiTheBugSlayer]

I was able to wrap my entire app in the scrolling container to get the window scrolling to work. The issue I am having is because the header is fixed positioning, when you drag an item to the top of the window, nothing happens. I have tried playing around with the strength, but that doesn't seem to help. It works just fine to try and scroll down and if I remove the fixed positiong of the header it works. Is there a way to get around this? Thank you in advance.
