Using Drupal blocks inside PB Content

Problem/Motivation

Creating PB Content with a paragraph using a Drupal block appears to duplicate the Drupal block.
That confused me. I am not a paragraph power user.

Steps to reproduce

Proposed resolution

Add to documentation that it is recommended to keep these blocks in the hidden region and enabled. In order to only show them inside the paragraph of the PB Content.

Remaining tasks

User interface changes

API changes

Data model changes
