The TouchExplorer was not taking into account the case with incative pointers while dragging. If one puts a finger down and then perfroms a dragging gestore the explorer tries to inject UP event for the end of the gesture upon every of the two dragging pointers going up instead only for one the first went up. bug:5476098 Change-Id: I20d2dd7bde7e016b0678a35d14cd068d9ff37023
