In “10.8.1 Leading and half-leading”, replace the last paragraph as follows:
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.The baseline of an 'inline-block’ whose ‘overflow’ property has a computed value of ‘visible’ is the baseline of its last line box in the normal flow, unless it has no in-flow line boxes, in which case the baseline is the bottom margin edge. The baseline of an inline-block whose ‘overflow’ property has a computed value not equal to ‘visible’ is the higher of either its bottom margin edge or the baseline of its last line box in the normal flow, unless it has no in-flow line boxes, in which case its baseline is the baseline is the bottom margin edge.
This avoids an undesirable visual difference between 'overflow: visible' and 'overflow: auto', in particular in the case when there is no visible scrolling mechanism, beause the height is sufficient.
