<!--
CSS2 states that:
  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.
  https://drafts.csswg.org/css2/visudet.html#propdef-vertical-align
This rule should apply only to 'inline-block', and not to normal block.
