Implicit return in arrow functions not considered for expressionCase etc

[Gama11]

With default settings, this:

class Main {
	public static function main() {
		var f = () -> switch (false) {
			case true: 1;
			case false: 0;
		}
	}
}

is reformatted to:

class Main {
	public static function main() {
		var f = () -> switch (false) {
			case true:
				1;
			case false:
				0;
		}
	}
}

This doesn't happen if you add an explicit return before switch, so I guess the implicit return that arrow functions have simply isn't considered here. That means this should affect other expression* settings too, not just expressionCase.
