Source/WebCore:
The position of internal shadow-DOM nodes were not being considered
when determining the snap position when TOUCH_ADJUSTMENT is enabled
for fine tuning the position of synthetic mouse events. This
restriction results in not being able to select the calendar picker
when input type=date, or to clear the search field for input
type=search.

LayoutTests:
Cannot open calendar picker for input type=date using a touch tap
gesture if TOUCH_ADJUSTMENT is enabled. When touch adjustment is
enabled, the position of a touch point is snapped to the center of an
element when generating synthetic mouse events. The position of shadow
nodes was not being considered when determining the snap position.
This test verifies that touch adjustment now considers shadow-DOM
when calculating the snap position.

Stop calling node() and deprecatedEditingOffset() in comparePositions
These make sure the alignment used in the first row of the span is correct when things like
the height of the cell and the height of the span are specified.
