In the Keyboard Support section, currently the following is listed:
Home Moves focus to first node.
End Moves focus to the last node that can be focused without expanding any nodes that are closed.

Question: does Home expand any nodes that are closed?

Also, none of the links with role="treeitem" causes a page to load either via keyboard or mouse.
