Container Wrapper Classes removed on next save

I am experiencing this too.

this actually needs some major refactoring

So no secret and we got permission to do so but this was forked from ckeditor_bs_grid and bootstrap has container options.

So here we need to to turn that default option to a checkbox to add the container.

Move the container class to that Div vs uswds_grid which isn’t a real uswds class

Try this

Going to go on a limb

Put a warning in the description this was a re write

There seem to be a few issues with this upgrade

1) There are a number of errors present. These appear even after a "drush cr".

2) After creating a page with a grid the wrapper classes are saved successfully, but when I go to edit the grid again a large black triangle appears in CKEditor. I can confirm this did not happen in 3.1.2.

3) Embedded Content appears broken. Any page with an existing Accordion returns an error like this:

Additionally, when clicking the "Embedded Content" button when creating a new node, there is a 500 error in the console.

I don't understand how #1 and #3 are related to this issue

Tested again, 1 and 3 were the result of upgrading with --with-dependencies, which upgraded doctrine/deprecations to and caused those errors.

2 is still present when upgrading without --with-dependencies.

But I can confirm the intended functionality of being able to save the wrapper classes seems to be working.

So I don't forget to take a look
