Safari Technology Preview 188 seems to pass all WPT tests: https://wpt.fyi/results/eventsource?label=master&label=experimental&aligned=&q=eventsource-constructor-url-bogus @Anne - anything to add or should I just go ahead and close with 'RESOLVED WONTFIX' (Since it was never confirmed) else I would've opted for 'RESOLVED CONFIGURATION CHANGED'.
WORKSFORME seems more reasonable then (or maybe INVALID), but this was probably wrong and then corrected.
