yes I see both, scroll started and end, even if I add a breakpoint to the position where the animation should stop, I go there. So the lines are definitely called: `Scroll Started Optional(NSEvent: type=ScrollWheel loc=(766.953,391.656) time=477849.7 flags=0 win=0x126815100 winNum=24768 ctxt=0x0 deltaX=0.000000 deltaY=-2.000000 count:0 phase=Changed momentumPhase=None) end NSEvent: type=MouseMoved loc=(1104.8,89.9805) time=477850.7 flags=0 win=0x126815100 winNum=24768 ctxt=0x0 evNum=21283 click=0 buttonNumber=0 pressure=0 deltaX=17.000000 deltaY=22.000000 deviceID:0x200000000000022 subtype=NSEventSubtypeTouch `
