This is the page of outdated templates. All looks well
But when i scroll down a bit, you see the header "OA" (name of a style) doesn't scroll down with the rest. Instead there is an open space between the "public" and the "footer" template. OA remaines in the same spot, whatever i do.
Somthing similar happens on the node-tree. You see how the last column doesn't stay in the viewport.
