    • This would be incredibly helpful. Being able to send wheel events programatically means I can then re-parent and forward mouse events selectively. For example, I want to be able to click on an element to interact with it, but scrolling should send the event along to the element behind it to be panned/zoomed.

    • Chrome 51 has this fixed – it no longer scrolls when the user-defined wheel event is dispatched :) Per the DOM spec (3.10) events are not action-causers, but notifications of an action already-in-process. Chrome was aware of this defect and has not finally fixed it.
