Forward-port 8474 to 10.0: If path parameter points to a folder, a document tab is opened

If path parameter is /content/documents, a document tab is falsely opened. It even has an Edit button.

See screenshot.

How to reproduce:
1. using archetype - go to CMS, select any document [e.g: path=/content/documents/archetype/content/sample-document] and make sure they are open in the editor.
2. change the path parameter to /content/documents (or any other folder path, e.g: /content/documents/administration)

expected behavior: no document editor tab should be opened following accessing a folder through path URL

current behavior: document editor tab was opened
