#3820 (ok 4.3) hide_db, only_db not working in left panel

[Timo Gurr]

$cfg['Servers'][$i]['hide_db'] = '^(information_schema|performance_schema|mysql)$';

Does work in 3.5.6 but doesn't seem to do anything in 4.0.0(_beta1). I also tried something simpler without regex but it also doesn't work, the databases are still displayed in the navigation sidebar.
