    protected function preparePlaceholderInInputTag(Tag $tag): Tag
    {
        if (
            $this->setPlaceholder
            && $tag->getAttribute('placeholder') === null

The method getAttribute() does not exist on Yiisoft\Html\Tag\Base\Tag.

        ) {
            $placeholder = $this->placeholder ?? $this->getAttributePlaceholder();

It seems like getAttributePlaceholder() must be provided by classes using this trait. How about adding it as abstract method to this trait?

            if ($placeholder !== null) {
                $tag = $tag->attribute('placeholder', $placeholder);
            }
        }

        return $tag;
    }
}
