Because polyglossia uses the new spelling patterns. If you use
ngerman for babel it would hyphenate wußte too, and with
\setdefaultlanguage[spelling=old]{german} polyglossia doesn't
hyphenate wußte.

Yes this is quite curious. Hyphenation before a ß seems to be
suppressed. But it works without problems if one add hyphenations
exceptions. \hyphenation{gei-ßeln}
