Steps to reproduce:
- Add a second user to the portal.
- Go to Content -> Documents and Media.
- Add a file.
- Share it with the user created before.
- Click on the file to open the preview page.
- Open the info panel.
- Click on Manage Collaborators.
- Remove the user.
- Click Save.
Expected: The collaborators list disappears from the info panel.
Actual: The collaborators list remains until the page is manually refreshed.
This works when performed in the info panel of the list view.
