I read current editor's draft of CSS Text Module Level 3.

It says about text-justify: inter-ideograph[1]:
> ‘inter-ideograph’
> Justification primarily changes spacing at word separators and between characters in block scripts. This value is typically used for CJK languages.

Block script is defined like following[2]:
> block scripts
> CJK and by extension all Wide characters. (See [UAX11]) The following scripts are included: Bopomofo, Han, Hangul, Hiragana, Katakana, Yi

UAX11 define U+3033 and U+3033 are wide characters.
Therefore, text-justify: inter-ideograph should separate U+3033 from U+3035..

However, Requirements for Japanese Text Layout define them as
inseparable characters[3].

I think separating U+3033 from U+3035 is odd behavior from Japanese perspective.
