1. Log in as admin user
2. Create a Site and add a page
3. Add a Web Content Display portlet on the page
4. Click Select Web Content
5. Open the dropdown on the Search field
6. Check the "My Sites" field, assert that the current site is present and is pre-selected by default
7. Exit the dialog, go to Admin > Site Administration > Users
8. Remove the admin user (that you are logged in with) from site members
9. Go back to the page and the portlet, Click Select Web Content, Open the dropdown again

Result: The current site is no longer available for selection in "My Sites" field

The issue is not present on master and 7.0, but since the UI was completely refactored there, there is no chance to find and backport anything specific.
