Gutenberg Publicize: Can't disable sharing to a shared social media account as an Author

[alisterscott]

When a social media connection is added to a simple site and is shared to an Author on the site, the author cannot disable publishing to the connection when posting content.

Steps to reproduce

1. You will need two accounts and a single simple site: User1 is owner and administrator of the site, User2 is added to the site as an author
2. A social media connection is added by User1 and the option to share to all administrators, editors and authors is ticked
3. As User2 can see shared account under social settings, also can add own social media account
4. When publishing content using Gutenberg as User2 - the shared account is listed but can't be disabled when publishing which means the user is forced to share to this social media account - this differs from the classic Calypso editor where it can be disabled

What I expected

To be able to not share content to the shared connection as an Author

What happened instead

I can't choose not to share content

Browser / OS version

Chrome and Safari macOS

Screenshot / Video

User 1 Shared Account

User 2 can see shared account and add own account

In Gutenberg - Author can't disable publishing to shared account

In Calypso Classic - Author can disable publishing to shared account

Manual testing new Gutenberg editor Jetpack features

@alisterscott I've removed this from Calypso Gutenberg Integration project since it's already assigned to Gutenpack. While it technically falls under the overall integration effort, it probably won't be handled by @Automattic/lannister, so I'm removing it from our board to avoid confusion.

Nice catch @alisterscott!

This seems to be an API issue, so I'll transfer it to the Jetpack repo.

Also, will come up with a fix shortly.

Seems like on WP.com we allow toggling the services to users with the publish_posts capability, while on Jetpack we do it for edit_others_posts capability. Since it makes sense for authors to be able to disable/enable a network before publishing, it makes sense to use publish_posts. Will file a PR in a bit.
