"The definition of fullwidth and halfwidth forms can be found on the Unicode consortium web site at [UAX11]. The mapping to fullwidth form is defined by taking code points with the <wide> or the <narrow> tag in their Decomposition_Mapping in [UAX44]. For the <narrow> tag, the mapping is from the code point to the decomposition (minus <narrow> tag), and for the <wide> tag, the mapping is from the decomposition (minus the <wide> tag) back to the original code point."

I don't understand this. If you map to decomposition mappings the characters are no longer full-width, right? How can your example abbr:lang(ja) { text-transform: full-width;  convert the ASCII characters in abbreviations in Japanese to their fullwidth variants so that they lay out and line break like ideographs?
