add attribute on generated <script> tag

[Edwin Diradinata]

What steps will reproduce the problem?

<?php $form = ActiveForm::begin(['id' => 'login-form']); ?>

    <?= $form->field($model, 'date_posted')->widget(DatePicker::classname()) ?>

    <div class="form-group">
        <?= Html::submitButton('Save') ?>
    </div>

<?php ActiveForm::end(); ?>

and it generated <script> tag for initiation of the widget component

What is the expected result?

but what I want is to add an attribute on the generated <script> tag,
for example <script attribute="here-the-new-attribute">
