User tabs remain Winter styled after attempt to revert.

My test user Selenium_user had been signed up for "Automatically enable all new beta features" on http://en.wikipedia.beta.wmflabs.org/

I want to revert the Winter styling because it causes failures in the automated browser tests.

In beta preferences I unchecked and saved "Automatically enable all... " and saved.

In beta preferences I unchecked "Winter..." and saved.

After that, I cleared cache, deleted cookies, and even checked starting a new browser instance with a profile known to be empty.

While the page tabs revert properly, the User links remain Winter. See screen shot.

High priority because I'd rather not update login for all the browser tests suites until the last responsible moment.
