To improve reliability of live streams (#59) on Safari. Safari was dropping the cookie from websocket update requests. (But it worked sometimes. I don't get why.) I saw folks on the Internet thinking this related to HttpOnly: * https://developer.apple.com/forums/thread/104488 * https://stackoverflow.com/q/47742807/23584 but I still see this behavior without HttpOnly. SameSite=Strict vs SameSite=Lax appears to make a difference. Try that instead. SameSite=Strict is pointless for us anyway as noted in a new comment. Turning off HttpOnly would be more unfortunate security-wise.
