Comment (by arthuredelstein):

 When I log into gmail, I can see with the Network Monitor that several 302
 redirects occur before we finally reach a 200 response at mail.google.com.
 One of these redirects is at account.youtube.com, and it includes a Set-
 Cookie header:

 It's clear that 302 redirects are Google's way of ensuring that when you
 log into gmail, you are also logged into youtube.

 This clearly looks like another case of #14085.
