Trying to login to the feedback site (https://feedback.minecraft.net) does not appear to work. After successfully having gone through the login form, the site still shows asthough I were logged out.

I'm using an old Microsoft Live account that otherwise still works. Logging into www.microsoft.com using the same credentials works fine and shows my gravatar at the top right. (same as on this site)

This issue is related to but not the same as WEB-850, where an error occurred after trying to login, which does not happen for me anymore.
