I have applied the patch file and below are some observations.
When we create the new folder and hit the enter then we are getting the below error.
TypeError: argument of type 'NoneType' is not iterable
I have just added the new control in "Import" dialog and observed that new control is getting added in new tab called "General". I think it should not create the new "General" tab.
"Select" and "Cancel" buttons font is different then other dialogs.
