While calculating the thumb value at SliderThumbElement::setPositionFromPoint() as the result of a (touch) event, the subpixel on result is off by one. position = offset.y() - (renderBox()->height() / 2) - trackBoundingBox.y() - renderBox()->marginBottom(); This is similar to bug 126658 failed case: fast/forms/range/slider-transformed.html fast/forms/range/slider-zoomed.html
