Re: [csswg-drafts] [css-text] Line breaking for ambiguous characters; e.g., U+2010, U+2013 (#4419)

@fantasai After discussing with Kobayashi-sensei, I need your help. Do you remember why we allow breaking before these code points for `normal`?

Kobayashi-sensei thinks these are rarely used code points in Japanese, but he feels more natural to prohibit breaking before them. Even if there were cases/reasons where we want to break before them, if it has side effects, changing would be fine.

I checked [JLREQ line break table], and found that it prohibits break before [cl-03]. I thought `normal` is a copy of JLREQ rules, but maybe we tweaked for some reasons I don't remember.

I think we can remove `normal` from this rule. Actually, other than this one, `normal` matches UAX#14. How about removing all rules for `normal` and defer to UAX#14? UAX#14 doesn't have `strict` / `loose`, so we can keep them, but `normal` does not seem to be necessary if we can match these 4 code points to UAX#14.
