    Source/WebCore:
    
    Update check for determining if a node responds to tap gestures.
    Previously, the cancel button was being discarded as a candidate for
    touch adjustment if the touch area clipped the text input region
    because the candidate pruning process failed to account for the cancel
    button having a default mouse handler.  Possibly an interim fix,
    depending on resolution to 92093.

    Add test for touch adjustment in the vicinity of a search cancel button.
    Prior to the patch, the cancel button was pruned as a candidate if the
    touch area clipped the input field.
