title: Yii2 - Textarea does not show linebreaks
body: <p>I'm wondering about that the default textarea of Yii2 does not show newlines per default. <strong>And</strong> the Yii2 model does not save the newlines into the DB.</p>
  
  <p>I didn't found anything in the Yii2 documentation, so hopefully you guys can help me - this is more than weird for me :-(</p>
