When splitting the arguments of a function call into separate lines and adding a // comment to them, the "," will be placed on the next line instead of the previous one.

For example this lines:

    function test() {
        callFunction(a, //comments
        b,//comments
        c);
    }

Will be formatted to:

    function test() {
        callFunction(a //comments
        , b//comments
        , c);
    }
