Disable top navigation bar hide on scroll when search results dropdown is open

This is just a small nitpick on my part but something that shouldnt be too difficult to do. Currently when you scroll down while the search results popup window is open the top bar hides itself and the popup window also slides up with it hiding part of it. In general this just looks kind of odd. My proposed solution is to keep the top navigation bar fixed on screen if the search results box is open.
