ECA doesn't recognize paragraph presave

I can't reproduce this, it's behaving as expected here. I have created a simple model which shows messages for the node and the paragraph, each after the pre-save event:

So, this is as expected and the pre-save event is being dispatched also for paragraphs. There must be something else in the Drupal instance that prevents this from working as you describe it.

What's the status on this?
