Re: [csswg-drafts] [css-text-3] Allow breaking anywhere when dictionary is missing for SEA scripts (#4284)

Not sure about panI10n.net rules but Lao syllable breaking has been fully implemented by Lao Script for Windows since about 1993 (usually using ZWSP insertion).  Excluding loan words, there are few ambiguities, and they are easily managed by *not* allowing a break if it would be ambiguous.  For Lao, as well as keeping grapheme clusters together, a break should never be allowed after a prefix vowel or before U+0EB2 LAO VOWEL SIGN AA, or either before or after  U+0EBD LAO SEMIVOWEL SIGN NYO.  Thai syllable breaking is much more difficult and requires a moderately large dictionary to be effective.
