Weird formatting of nested array comprehension

[Gama11]

Input file

class Main {
	static function main() {
		var grid = [
			for (x in 0...gridSize.x + 1) [
				for (y in 0...gridSize.y + 1) {
					new Point(x, y);
				}
			]
		];
	}
}

Broken output

class Main {
	static function main() {
		var grid = [
			for (x in 0...gridSize.x + 1)
				[
					for (y in 0...gridSize.y + 1) {
						new Point(x, y);
					}
				]];
	}
}
