Select2 error when using plugin option "allowClear"

[SegaSh99]

Prerequisites

• I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• The issue still exists against the latest master branch of yii2-widget-select2.
• This is not an usage question. I confirm having read the widget documentation and demos.
• This is not a general programming / coding question. (Those should be directed to the webtips Q & A forum).
• This is not a source plugin (select2) issue. (Those should be directed to the plugin issues repo).
• I have attempted to find the simplest possible steps to reproduce the issue.
• I have included a failing test as a pull request (Optional).

Steps to reproduce the issue

Create a Select2 filter with the "allowClear" plugin option and without "placeholder" option. Example:

<?= $form->field($model, 'attribute')->widget(Select2::class, ([
    'data' => [1 => 1, 2 => 2],
    'pluginOptions' => [
        'allowClear' => true,
     ],
])) ?>

Expected behavior and actual behavior

When I follow those steps, I see the following error in the console:

Uncaught TypeError: Cannot read properties of undefined (reading 'id')
    at AllowClear._handleClear (select2.full.js:1907:40)
    at DecoratedClass._handleClear (select2.full.js:598:32)
    at HTMLSpanElement.<anonymous> (select2.full.js:1881:14)
    at HTMLSpanElement.dispatch (jquery.js:5145:27)
    at elemData.handle (jquery.js:4949:28)

I was expecting: the Select2 field will be cleared.
