After uploading an entire folder, auto-refresh when clicking back button

Steps to reproduce:

1. Create a new folder (F1)
2. Click on New File button
3. Check Enable folder selection
4. Click on Choose files
5. Select an entire folder from your PC
6. When the upload is finish, click back

Now you should see in your tree-file the folder that you uploaded as a subfolder of folder F1. In order to see this, you have to manually refresh folder F1. It would be nice if it would auto-refresh when you click Back button.
