Scroll-panes should not filter input events

[scruffyvoltherder]

I am using a scroll-pane to manage horizontal scrolling, but i am also using custom input events with mouse-wheel-up and mouse-wheel-down in order to manage vertical scrolling. ( vertical scroll policy = none. Workaround for table headers and selective updates).

The problem is that when the mouse is within the scroll-pane, when i move the mouse wheel, my custom inputs don't get triggered.
Would it be possible to make it so that scroll-panes don't block input events on the mouse wheel?
