We fire a dblclick for double tap in Edge when it doesn't result in a zoom (e.g. `touch-action: manipulation`) as @patrickhlauke suggests.  The zoom isn't considered a default action for dblclick in Edge though, as the zoom initiates on the second pointerdown (whereas the dblclick doesn't fire until after the second pointerup).

Using `touch-action: manipulation` is the recommended way to explicitly indicate that you intend to handle non-scrolling or non-continuous-zooming actions per PE level 1, which would include taps and double-taps.  Varying behavior on event registration would be an unpleasant side effect that doesn't have much precedent AFAIK.
