Initial Filters is not respected when array type filter

When the user supplies an array type filter with initialFilters, the initialFilters are never used. The filter logic has the following code:

	  const urlValue = isArrayFilter ? searchParams?.getAll(key) : searchParams?.get(key);

      // eslint-disable-next-line no-nested-ternary
      loadedFilters[key] = urlValue
        ? (isArrayFilter && !Array.isArray(urlValue) ? [ urlValue ] : urlValue)
        : initialFilters[key];

The issue is that searchParams.getAll returns an empty array when key doesn't exist, so the truthy check on urlValue evaluates to true even though nothing is set.

This can be resolved by checking the length of the array when isArrayFilter is true

Comience con la lógica de filtros mostrada en el issue y siga cómo se cargan los filtros de array y initialFilters cuando falta la clave de URL. Reproduzca el caso con un filtro de tipo array y verifique que los valores iniciales configurados se conservan cuando no existen valores en la URL.
