Sort order is not respected for Formkit ElementSelectInputs

[superextinct]

Describe the bug

In the current implementation, domToModel() is only called after elements have been added or removed, but not when elements are re-ordered.

Steps to reproduce

Render an elementSelect Input:

public function defineGeneralSchema(): array
{
    return [
        SchemaHelper::elementSelectField([
            'label'=> 'Schritte',
            'help' => 'Einträge auswählen, die als Schritte angezeigt werden sollen.',
            'name' => 'sourceElements',
            'validation' => 'required',
            'required' => true,
            'config' => [
                'jsClass' => $this->cpInputJsClass,
                'elementType' => static::elementType(),
                'limit' => null,
            ],
            'selectionLabel' => Craft::t('app', 'Choose'),
        ]),
    ];
}

Add and re-order elements, apply the field settings and observe the sort order has been reset to the insertion order.

Additional context

For "Entries" fields, this would also require more changes. In my custom field, I'm doing this:

public function getElementsQuery(): ElementQueryInterface
{
    $query = parent::getElementsQuery();

    // When elements are manually curated, the parent applies orderBy('title ASC') which
    // destroys the user-defined sort order. Use fixedOrder() to preserve it.
    if (!empty($this->sourceElements)) {
        $query->orderBy(null)->fixedOrder();
    }

    return $query;
}

public function modifyFieldSettings(array $settings): array
{
    $settings = parent::modifyFieldSettings($settings);

    // The parent re-queries sourceElements without fixedOrder(), returning elements in DB
    // order instead of the user-defined order. Re-run with fixedOrder() to fix that.
    if ($ids = ArrayHelper::getColumn($this->sourceElements, 'id')) {
        $elements = static::elementType()::find()->id($ids)->fixedOrder()->status(null)->all();

        $settings['sourceElementsOptions'] = array_map(fn($el) => [
            'label' => $this->getElementLabel($el),
            'value' => $el->id,
        ], $elements);

        $settings['sourceElementsHtml'] = Craft::$app->getView()->renderTemplate(
            'formie/_includes/element-select-input-elements',
            ['elements' => $elements]
        );
    }

    return $settings;
}

Fixed for the next release. To get this early, run composer require verbb/formie:"dev-craft-5 as 3.1.15".
