After checking the GTK implementation and the common code, I don't see how we could fix this in short. The problem is that we need to track the element with the touch_down event. Then we need to check if the touch_up event correspond to the same element and then issuing a click() event. Question is also, do we need to synthesize the click event? According https://w3c.github.io/uievents/#click this is not the case.
