Content Type under one site showing up in other sites

Problem Statement

See attached screen grab.

When creating a content type under a specific site, the content type shows up in other sites. Users can use that content type in the other sites to create a piece of content, but that content does not show up in the site, it shows up in the site the content type has been created under. This is confusing to end users.

If a content type is created under a specific site, it should only be available to that site.

Steps to Reproduce

Please see video

1. Make sure instance has at least two sites
2. Create content type and set the site/folder field for the content type to one specific site
3. Use the site picker to change the site to a site that is NOT the site the content type has been created under
4. Create a piece of content using the new content type
5. You will not see the new piece of content in that site
6. Navigate to the site the content type was created under
7. You will be able to see the content created in the other site

Acceptance Criteria

When a content type is created under a site, it should only be available to that site, you should not be able to view it or create content from it in other sites

EJ Americas customer brought this issue up in a call. I replicated it on our demopm instance. It is not a showstopper but it is causes confusion and degrades the perception of our application.

Start by reproducing the issue with two sites, a site-specific content type, the site picker, and a created content item. Trace how the content type's site/folder selection affects availability across sites. Done means the type cannot be viewed or used to create content from any other site, while remaining available in its own site.
