language shoudl always be an AtomicSTring, surprised defaultlanguage isn't. 
Maybe beacuse it's used on more than one thread?

It does not look like it is used in more than one thread so I will give it a
try.

     else {
         AtomicString computedLocale = computeInheritedLanguage();
         parameters.locale = computedLocale.isEmpty() ? AtomicString(defaultLanguage()) : computedLocale;
     }
 
     StepRange stepRange = createStepRange(RejectAny);
     if (stepRange.hasStep()) {
         parameters.step = stepRange.step().toDouble();
         parameters.stepBase = stepRange.stepBase().toDouble();
     } else {
