fast/text/cjk-multi-codepoint-cluster-vertical.html Image diff. Test added in r271425 (bug220536). The glyph is rendered in the correct orientation but there is a small positioning difference between the actual (writing-mode vlr) and the expected htmls results. Dumping the render trees for each one we have the following diff (top: text in vertical mode and bottom, the reference horizontal text). 10,12c10,12 < RenderBlock {DIV} at (0,36) size 100x100 < RenderText {#text} at (-6,0) size 111x100 < text run at (-6,0) width 100: "\x{30D5}\x{309A}" --- > RenderBlock {DIV} at (0,36) size 784x100 > RenderText {#text} at (0,-6) size 100x111 > text run at (0,-6) width 100: "\x{30D5}\x{309A}"
