diffConfig always returns true if modeBarButtons (array of array) is populated

diffConfig function has bug where it always returns true if modeBarButtons (array of array) is populated. This results in unnecessary re-rendering. The function should check if the array member is array inside a for loop, It should be -

/*

• simple diff for config - for now, just treat all changes as equivalent
  */
  function diffConfig(oldConfig, newConfig) {
  var key;

  for(key in oldConfig) {
  if(key.charAt(0) === '_') continue;
  var oldVal = oldConfig[key];
  var newVal = newConfig[key];
  if(oldVal !== newVal) {
  if(Lib.isPlainObject(oldVal) && Lib.isPlainObject(newVal)) {
  if(diffConfig(oldVal, newVal)) {
  return true;
  }
  } else if(Array.isArray(oldVal) && Array.isArray(newVal)) {
  if(oldVal.length !== newVal.length) {
  return true;
  }

           for(var i = 0; i < oldVal.length; i++) {
               if(oldVal[i] !== newVal[i]) {
   				**if(Array.isArray(oldVal[i]) && Array.isArray(newVal[i])){
   					if(diffConfig(oldVal[i], newVal[i])) {
   						return true;
   					}
   				}							
                   else** if(Lib.isPlainObject(oldVal[i]) && Lib.isPlainObject(newVal[i])) {
                       if(diffConfig(oldVal[i], newVal[i])) {
                           return true;
                       }
                   } else {
                       return true;
                   }
               }
           }
       } else {
           return true;
       }
   }
  

  }
  }

e.g Config object used -

const plotlyConfig: Partial = {
responsive: true,
displaylogo: false,
displayModeBar: true,
doubleClick: false,
showTips: false,
scrollZoom: false,
modeBarButtons: [
[
'select2d',
'lasso2d',
'zoom2d',
'pan2d',
'resetScale2d',
],
],
locale: language,
locales: locales
}

Localiza la función diffConfig y utiliza el ejemplo plotlyConfig con arrays modeBarButtons anidados como caso de reproducción. Compara arrays anidados equivalentes y verifica que las configuraciones sin cambios no se notifiquen como diferentes, evitando el re-renderizado innecesario; el issue no indica ningún archivo ni prueba.
