ISBAT delete the content of the second column in the Features Block

[ersatzpenguin]

Describe the bug:

ISBAT delete the content of the second column in the Features Block and not have it regenerate the next time I edit the page the Features Block is on.

To reproduce:

1. Add the Features Block to a page.
2. Delete the content of the second column.
3. Publish the page.
4. View page to confirm it was indeed deleted.
5. Open page in the editor again.
6. See error.

Expected behavior:

I expected the content of the Features block to respond to editing—that deleting the content of the second column would result in it staying deleted when I re-opened the editor. This is helpful when creating a series of Features blocks and having an odd number of "Features" to add to the blocks.

Verified and agree this is a very odd UX. Not only should we properly maintain the edits we need to fix the styling when there is only a single column.
