Pagination using "nextpage" does not work with Sensei lessons

[alexsanford]

Steps to Reproduce

1. Create a new lesson or edit an existing one.
2. In the Editor, choose the "Text" view
3. Between some paragraphs, add the <!--nextpage--> marker to indicate that the content should be paginated.
4. Save and view the lesson on the frontend.

What I Expected

To see pagination links in the content, or at least to see the full content (i.e. for pagination to be ignored)

What Happened Instead

Only the content up to the first <!--nextpage--> was displayed.

This issue only occurs when a page builder plug-in (WPBakery Page Builder [formerly Visual Composer}, Elemental, etc) is installed and active.

Steps to reproduce need one additional step

1. Install and activate a page builder plug-in
2. Create a new lesson or edit an existing one.
3. In the Editor, choose the "Text" view
4. Between some paragraphs, add the marker to indicate that the content should be paginated.
5. Save and view the lesson on the frontend.

What I Expected To see pagination links in the content, or at least to see the full content (i.e. for pagination to be ignored)

What Happened Instead Only the content up to the first was displayed.

MORE: Disable the page builder plug-in and pagination occurs in the frontend display at the marker(s).

I wasn't using a page builder on my test site when I reproduced this, FYI.

@jcmason4 We have this scheduled for the 1.12.1 release. The 1.12.0 release is due out in a couple of weeks. After that, we'll start working on 1.12.1. Thx!
