Description:
If a web content structure has a web content selector field, when creating new web content using that structure, the available pieces of content to select should be those articles from the current site as well as articles from the Global and parent site. As it stands, only those articles created in the current site will be displayed and available (and not those from Global or parent).

Steps to Reproduce:
1. Go to Global site / Content / Web Content
2. Create a web content structure with a web content field
3. Create a web content template for the structure in Step 2
4. Create an article with the Basic Web Content structure
5. Create an article with the structure created in Step 2
6. Use the Web Content Selector, you should be able to see the article created in Step 4
7. Go to Guest site / Content / Web Content
8. Create an article with the structure created in step 2
9. Click the Web Content Selector

Expected Results: 
You should be seeing article created in Step 4 from the Global site (with scope as "All")

Actual Results: 
The article created in Step 4 doesn't appear as a selection option, nor in the search results
