 * reflect the real Y position of child mean the dependency get a better APROXIMATION of the real
 * Y. This was causing that FAB some times doesn't get unhidden.
 * @param child the FAB
 * @param dependency NestedScrollView instance
 * @return Dy betweens those 2 elements in Y, minus child's height/2
