The CSS Text Level 3 Editor’s Draft (CVS Revision 1.6 <http://dev.w3.org/cvsweb/~checkout~/csswg/css3-text/Overview.html?rev=1.6&content-type=text/html;%20charset=iso-8859-1>) has been updated to say:

“If emphasis marks are drawn for grapheme clusters for which ruby is drawn in the same position as the emphasis mark, the ruby should be stacked between the emphasis marks and the base text. In this case, the position of the emphasis marks for a given element should be determined as if all grapheme clusters have ruby boxes of the same height as the highest ruby box in the element. If the UA is not capable of drawing ruby and emphasis marks on the same side, the UA may hide ruby and draw only emphasis marks.”

The suppression behavior introduced in <http://trac.webkit.org/changeset/75257> (for bug 51267) needs to be reverted and the above behavior implemented instead.
