(Sorry for early enter of #4. Please ignore it)

No. According to Unicode standard, for the puctucations in CJK vertical text, the glyphs should be substituted with the corresponding vertical forms of them according to the GSUB table in the font. The new layout test is testing this behavior. It's a bug that the glyphs are not properly substituted.
