Couple of issues dealt with by this CL:
1) We should be starting the gesture from near the bottom of the page
instead from the top (as it moves upwards)
2) In TouchInputTransferAcrossReactivation, we might get some scrolling
in the main page before the first activation. We should be checking
to see if it has scrolled more than that amount after reactivation
