I've added to the definition of 'text-wrap: normal':
   "Line breaking behavior defined for the WJ, ZW, and GL line-breaking
    classes in [UAX14] must be honored."

And to the definition of 'text-wrap' generally:
   "For all values, line-breaking behavior defined for the BK, CR, LF,
    CM NL, and SG line breaking classes in [UAX14] must be honored."

That covers all the non-tailorable classes except for SP.
