Style out of place after update to V2.2.3

Prerequisites

• [x] I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• [x] The issue still exists against the latest master branch of yii2-widget-select2.
• [x] This is not an usage question. I confirm having read the widget documentation and demos.
• [x] This is not a general programming / coding question. (Those should be directed to the webtips Q & A forum).
• [x] This is not a source plugin (select2) issue. (Those should be directed to the plugin issues repo).
• [x] 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 multi select field in view:

$data = ['aaaa', 'bbbb', 'cccc (very long very long)', 'dddd (very long text)'];
echo $form->field($model, 'field1')->widget(Select2::classname(), [ 
        'data' => array_combine($data, $data),
        'options' => [
            'placeholder' => 'Select...',
            'multiple' => true,
        ],
    ]);

Expected behavior and actual behavior

When I follow those steps, I see... Selected items aren't aligned to left: When selected items have long text, only 1 is shown, the other one is hidden:

I was expecting... (downgrade to V2.2.2)

Cannot reproduce your issue - seems you are using MULTIPLE select feature. Cross check the demos page for multiple selection where it works fine. You may want to check if you are not having a caching issue on your environment running outdated/stale assets. After update to a new select2 release, clean up web runtime cache and runtime assets and also your browser cache and retry,

While there are no issues from the demo page, this issue is reproducible with a brand new project with just a form. Original tests were done on Chrome, I have now tested on Safari and Firefox as well - no issue with V2.2.2 but same issue with V2.2.3 across these browsers. Runtime assets and caches and browser caches were cleared after updating the lib.
