What is the problem?
For logged in users with autoblocks against their users, we are no longer setting block cookies on RawAction (action=raw).
The change was introduced in T233594.
Steps to reproduce problem
On wikis with $wgCookieSetOnAutoblock set to true (should be on most production and beta wikis).
- Create an autoblock against $user (i.e. in Special:Block check the option "Automatically block the last IP address used by this user...")
- Login as $user
- For an existing article $foo, navigate to $foo?action=raw
Expected behavior: A cookie called something like enwikiBlockID is set
Observed behavior: The block cookie is not set
