Meta breaks anon obj

[kevinresol]

Describe the bug

When a meta is applied on anon object, the space after field name will be removed. (the space right after the status: in example below)

Input file

class Main {
	static function main() {
		return @patch {
			status:InProgress(v),
		}
	}
}

Broken output

class Main {
	static function main() {
		return @patch {
			status:InProgress(v),
		}
	}
}

Expected output

class Main {
	static function main() {
		return @patch {
			status: InProgress(v),
		}
	}
}
