[TIMOB-19610] String.format not IEEE printf compatible

I am expecting:

console.log ( String.format("Third: %3$s, Second: %2$s, First: %1$s", 'First', 'Second', 'Third') );

to print: Third: Third, Second: Second, First: First But instead it prints: Third: First, Second: Second, First: Third The position indication using % is ignored.
