PHPStorm switch statement 'break' indenting

PHPStorm switch statement 'break' indenting

PHPStorm is a very nice IDE, but it does one thing that annoys me.
I (and my team) write our switch statements like so:
switch ($foo) {
case 'a' :
// some code
break;
}
PHPStorm auto-corrects this to be
switch ($foo) {
case 'a' :
// some code
break;
}
Note that the break is indented along with the code. I don't want this to
happen.
I've looked in the code style section, but the only option for switches is
to indent the case branches.
Does anyone know how stop PHPStorm from doing this?
