r12a has just created a new issue for 
https://github.com/w3c/csswg-drafts:

== [css-text] cursive shaping breaks and typographic characters ==
8.3. Shaping Across Element Boundaries
https://drafts.csswg.org/css-text/#boundary-shaping

> for any box whose boundary separates the two typographic character 
units

i'm not clear how typographic units are relevant here – in fact, i 
think it may be incorrect to invoke them.  Apart from the fact that 
what constitutes a typographic unit is particularly vague here, i 
think that actually we just want to say "for any box whose boundary 
separates two characters", where character refers to Unicode code 
points.  For example, these rules should presumably apply to 
diacritics (it is a common use case to want to colour diacritics or 
accents differently from a base character), or a part of a grapheme 
cluster.

(See the tests at 
https://www.w3.org/International/tests/repo/results/css-text-shaping.en.html#diacritics
 for examples that actually show browsers applying the same behaviour 
to diacritics as to normal letters.)
