Re: [csswg-drafts] [css-text-3] Insufficient normative reference to UAX14 for the ID line breaking class

>From the teleconf:

Not normatively requiring UAX14 is intentional, because the rules are 
not only complex, but also not ideal. They are a good baseline, but 
not necessarily something that must be followed to the letter.

The argument against inlining into our spec some simplified statements
 like the one I proposed is that including such rules would be a 
significant scope increase to css-text, and not one we are well 
equipped to handled.

However, the spec does have a requirement that customary line breaking
 rules be followed. This is vague, but it is normative, and by group 
consensus can be used to justify certain obvious line breaking 
behaviors in tests, even if they are not explicitly spelled out 
individually in the spec. For instance, this is sufficient to expect 
wrapping opportunities between two kanji, and to depend on this in 
tests.

I'll use this to simplify the tests I proposed in 
https://github.com/w3c/csswg-test/pull/1135.
