hand-controls component : most events fire incorrectly or not at all on oculus quest

hand-controls component animation and gestures work fine but most of the js events are problematic when compared to the api in the docs here: https://aframe.io/docs/1.0.0/components/hand-controls.html

gripdown -- fires when grip button is pressed, regardless of other fingers. Is this the underlying oculus-touch-controls event, not a new gesture event ?
gripup -- fires when grip button is released, regardless of other fingers. Is this the underlying oculus-touch-controls event, not a new gesture event ?
pointup, pointdown, thumbup, and thumbdown never fire
pistolstart -- fires when thumbup is expected
pistolend -- fires when thumbdown is expected

Start with the hand-controls component and compare its event behavior against the API documentation linked in the issue. Reproduce the reported cases using the provided Oculus Quest test URL, then verify that grip, point, thumb, and pistol events match the documented behavior on Oculus Browser.
