Invalid definition item state in Bootstrap Nav class

[yii-bot]

Moved here by @samdark.

What steps will reproduce the problem?

$menuItem='posts';
echo Nav::widget([
'items' => [
['label' => 'Posts', 'url' => ['/posts/index'], 'active' => $menuItem == 'posts'],
['label' => 'Services', 'active' => $menuItem == 'services', 'items' => [
['label' => 'Petitions', 'url' => ['/petitions/index'], 'active' => false],
]],
],
'activateItems'=>true,
'encodeLabels' => false,
'options' => ['class' => 'nav navbar-nav'],
]);

What is the expected result?

The Item Petitions in dropdown must not have active css

What do you get instead?

dropdown item has css attribute class="active"

Additional info

original code:
protected function isChildActive($items, &$active)
{
foreach ($items as $i => $child) {
if (ArrayHelper::remove($items[$i], 'active', false) || $this->isItemActive($child)) {
Html::addCssClass($items[$i]['options'], 'active');
if ($this->activateParents) {
$active = true;
}
}
}
return $items;
}

Condition in line if (ArrayHelper::remove($items[$i], 'active', false) || $this->isItemActive($child)) {
is not correct. Problem is of using operator ||
