[ Upstream commit 8f529ff912073f778e3cd74e87fb69a36499fc2f ]
Set features can have multiple features turned on|off in a single call. Grouping these all in an if/else means after one condition is met, other conditions/features will not be evaluated. Break the if/else statements by feature to ensure all features will be handled properly.
