@Nate, I think you misunderstood.
The bug is this:
Expected:
- mousewheel in the dopesheet area should scroll up and down. Or do nothing if there's not enough dopesheet items to scroll up and down.
- mousewheel in the dopesheet time strip should zoom the dopesheet.
Bug:
- if you mousewheel on the dopesheet and there's not enough dopesheet items to scroll up and down (or it's empty), the VIEWPORT will zoom in and out.
That's definitely not intended. The viewport should zoom in and out only if the mouse is over the viewport. At the very least, mouse wheeling over the dopesheet shouldn't cause the viewport to zoom in and out, 'cause the user would expect that action to scroll the dopesheet only, as it already does if there are enough items in the dopesheet.
