Remove the support for "hover: on-demand" and "any-hover: on-demand" media queries. The "on-demand" value used to satisfy for the pointing devices that, for example, "can't normally hover, but will activate hover on a long press". The "on-demand" value for hover/any-hover media queries has been removed from the spec in early 2016.
