Re: Baseline of inline-block elements

Alright, here’s some new language:

"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 at the block’s initial scroll position, unless it has no in-flow line boxes, in which case its baseline is the baseline is the bottom margin edge.”
