Fix inline-block baseline with overflow: <not visible>

Fix inline-block baseline with overflow: <not visible>

They should align to the bottom of the margin box.
   The baseline of an 'inline-block' is the baseline of its last line
   box in the normal flow, unless it has either no in-flow line boxes or
   if its 'overflow' property has a computed value other than 'visible',
   in which case the baseline is the bottom margin edge.
