Instead of initializing the default grab when the device class is enabled, initialize it on object initialization. This way other device classes can still grab the pointer, as if there was one. This may be useful for example if a touch grab is active and a mouse is connected. This also makes it possible for popup grabs, which currently use a pointer grab for controlling, to be triggered by touch devices, while still holding an active pointer grab. https://bugzilla.gnome.org/show_bug.cgi?id=771305
