UIDocumentBrowserViewController allows the user to switch between a list and a grid view, which is great. The mode change however is done without any animation, which could be improved.

Steps to Reproduce:
1. open the attached DocumentBrowser-based app
2. open the "Browse" Tab and create a few new documents
3. Tap on the icon to switch between grid and list view

Expected Results:
There is a nice transition between grid and list view, similar to the one in the "PDF Viewer" App by PSPDFKit (The document preview images animate from their respective position in list view to grid view and vice versa).

Actual Results:
No animation, the view simply changes

iOS 11b1
