Should Mark Jhon Sta.Ana read family Sta.Ana, the saint particle glued to its surname? #1071

parse("Mark Jhon Sta.Ana") gives family Jhon and suffix Sta.Ana. Written with a space, Mark Jhon Sta. Ana gives middle Jhon, family Sta. Ana, the reading #725 (rules/P10's saint clause) settled. Juan dela Cruz Sta.Maria likewise gives suffix Sta.Maria.

Filipino writers often glue the saint particle to the surname it opens (Sta.Ana, Sta.Maria, Sto.Tomas). The glued token is two dotted chunks, so rules/S3 reads it by shape as an unlisted dotted suffix when a word is to spare (Policy.unlisted_dotted_suffixes, on by default). With no word to spare it stays the family (Juan Sta.Ana → family Sta.Ana). The vocabulary never sees it: sta and sto are listed, but the token is one word.

Questions:

• Should a dotted token whose first chunk is a listed saint particle (sta., sto.) read as the particle and the name it opens, the way the spaced twin does, instead of S3's shape reading?
• If so, does the token split into two words (as Should John Smith, MD - PhD split its suffixes without a declared delimiter, and can suffix_delimiter be deprecated? #889's glued delimiters part a token), or stay one family word?
• Does the same hold for other glued particle spellings (Sn.), given that St.John is already one name word under capitalized() lowercases a letter that should stay capital, after a period (J.R.R. → J.r.r.) or after an ayn (ʿAlī → ʿalī) #838?
