// coordinate, if it is not found in any of the touch events received so far.
// But during page navigation, touch event coordinates are empty and so first
// click event at any coordinate will be considered ghost click and will be
// prevented.
// We are passing 0,0 as params, since coordinate is compulsory. It doesn't
// really matter.
