select box not fits it content size in bootstrap5 mode and multiple values

[spo0okie]

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

1. use bootstrap5 + multiple value select2
2. select as many values as not fit in one row
3. values renders out of select box
4. select window still can stretch if items rows count grows, but it stretches to incorrect row count
   

<?= $form->field($model, 'techs_ids')->widget(Select2::className(), [
	'data' => \app\models\Techs::fetchNames(),
	'options' => ['placeholder' => 'Выберите оборудование',],
	'toggleAllSettings'=>['selectLabel'=>null],
	'pluginOptions' => [
	    'allowClear' => true,
	    'multiple' => true
	]
]) ?>

Isolating the problem

Dont know how reproduce PHP code anywhere like jsBin
I tried to reproduce it in raw select2, but it works fine

if set display property of <ul> item to "inline-block"
<ul class="select2-selection__rendered" id="select2-services-techs_ids-container" style="display: inline-block;">
then it renders more accurate, but search area makes additional row because it not inside <ul> item in BS5 mode:

in BS3 it was inside <ul>:

and was working fine
