I agree. Since CSS Text Level 3 doesn't define where line breaking opportunities occur, we should make this definition as diff, just like we do for the line-break property.

UAX#14, 8.2 Examples of Customization, Example 3[1] states the behavior for Korean. The referenced material doesn't seem to be available online, unfortunately, but it states:

> Only the intersections of ID/ID, AL/ID, and ID/AL are affected

It looks to me that prohibiting break opportunities for these combination gives what we want here.
