Hyphenation issue after apostrophe?

Observed

grou-pe d’-hommes (French, 0x2019)
grou-pe dʼ-hommes (French, 0x02BC)
grup d’-ho-mes (Catalan, 0x2019)
grup dʼ-ho-mes (Catalan, 0x02BC)

I am getting line breaks with an hyphen after the apostrophe (whether using the 0x02BC apostrophe or the 0x2019 quote mark: I thought this could have been my issue initially, with received texts from different software having one or the other, but they behave the same apparently).

Expected

It does not seem to me that the hyphenation point is legit. Seems to occur in more than one language (e.g. French and Catalan above).

The second commit in the above PR fixes the issue for U+2019... A mere typo in the code ;)

U+2019 "is preferred where the character is to represent a punctuation mark" - so this seems sufficient.

U+02BC "is preferred where the apostrophe is to represent a modifier letter (for example, in transliterations to indicate a glottal stop)" - so is not appropriate anyway.

EDIT. No it's a mess, linked to #687

FWIW

• The "quote" category is ambiguous according to the standard,
• ICU is having issues for languages using it as French, perhaps Italian (and Catalan, they don't mention it), as per e.g. https://unicode-org.atlassian.net/browse/CLDR-6665 and https://unicode-org.atlassian.net/browse/ICU-21854
