[css-counter-styles-3] fallback for cjk-earthly-branch and cjk-heavenly-stem

[vitorroriz]

As it is being discussed in #8596, it seems the right system for these styles is fixed. With that, the fallback for them becomes more relevant, given they defined just a few symbols (10 and 12). The styles don't explicitly define a fallback, so it is decimal.

I have no knowledge on CJK languages, but I'm wondering if decimal is the best fallback for them. For example, other CJK related styles have cjk-decimal as fallback. So I'd like to discuss if this (or another style) would be a better fallback option here.

<TabAtkins> seems reasonable to me too
<emilio> fantasai: seems reasonable, we should make the change and republish
<emilio> miriam: objections, anyone need more context?
<fantasai> emilio: would like someone familiar with cjk to look at it, but otherwise seems fine
<fantasai> +1 TabAtkins
<fantasai> TabAtkins: These fall back to cjk-decimal due to matching fullwidth
<emilio> TabAtkins: all fall back to cjk-decimal because of full-width, same applies to these
<emilio> RESOLVED: Change fallback for cjk-earthly-branch and cjk-heavenly-stem to cjk-decimal instead of decimal
<fantasai> RESOLVED: Republish CR
