What is the problem?
Missing information described in w3c/uievents#181 (comment)
And the change in Firefox caused by Intent to ship: Return pixel deltas in wheel event if deltaMode is not checked by authors, that modify the behavior to the following, decided per event:
If
deltaModehas been accessed, then the original delta mode and deltas are reported.If
deltaModehas not been accessed, and it'sDOM_DELTA_LINE, accessing any of the deltas cause the event to always reportDOM_DELTA_PIXELS, and the deltas get converted to pixels using thefont-sizeof the target element.For more information see:
