Comment:

 Fixed in [dotorg12451]:

 > Delete user data in the 'users' cache group on meta data changes.
 >
 > We have to do this because bbPress 1.x uses BackPress which appends user
 meta to the user object and stores it in the 'users' cache group, see
 https://backpress.trac.wordpress.org/browser/branches/bbpress-1.0-backpress/includes/class
 .wp-users.php?marks=467#L427.
 > `WP_User::init()` allows to initialize a new user object with any
 arbitrary data. In this case it will be bbPress'/BackPress' outdated user
 meta.
 >
 > WordPress uses a custom cache group for meta data so it doesn't delete
 the data in the 'users' cache group by default.
 >
 > This plugin can be removed once all bbPress 1/BackPress-reliant stuff is
 gone.
 >
 > Fixes #meta2034, #meta1980.
