How do I use pointer-events to react only to scrol

问题:

Is it possible to set pointer-events to only react to scrolling or drag on a touch-pad? I have a div 'in the way' for scrolling a complex html arrangement* and I would like to know if I can limit the pointer events to only react to scroll / mouse wheel actions.

I am interested in knowing whether I understand this correctly. If pointer-events:none; means that all events are void, how can I kill all events but leave one active?

I have set up an HTML area that is bigger than the box it fits in, but if I were to show the scroll bar, it would seem higher than it should be because of a pop-up (position:top) element. This area still needs to be scrolled so to achieve this I have used jQuery to make my 'box to scroll' follow an invisible div within a div:

<div id="scrollcontrol"style="overflow-y:auto;overflow-x:hidden;position:absolute;
   top:12px;left:180px;width:40px;height:1300px;">
   <div id="catscrollpos"style="position:absolute;
    top:0px;width:200px;height:2250px;">
   </div>
</div>

Script

$('#scrollcontrol').scroll(function({
  $('#rangetable').css({
  'top':$('#catscrollpos').position().top+'px'
  });
});

As for specification in the docs:

When an element has applied pointer-events: none;

The element is never the target of any mouse events and any events are void;

Please look at this demonstration:

Events are not being fired, you cannot even scroll the container.
