Braces are not added when adding second parameter to lambda.

Steps to reproduce:
1) have a code:
@FunctionalInterface
public interface Function {
    
    static Function idn = a -> a;
    
    String convert(String a);
        
}

2) change method parameter of convert method, add parameter
->
@FunctionalInterface
public interface Function {
    
    static Function idn = a, par1 -> a;  // here should be (a, par1) -> a
    
    String convert(String a, Object par1);
    
    
}
