ext-edit respectively focus handling: Internet Explorer scrolls briefly to the top/left of the tree container element after editing a node title if the tree container is partially outside the viewport

Internet Explorer sometimes (e.g. after editing a node title) scrolls briefly to the top/left of the tree container element if the tree container is partially outside the viewport and then to the node that should actually be focussed.

The reason for this seems to be the short-term focus on the tree container (in nodeSetFocus and ext-edit editEnd).

I think, the focus on the tree container should only be set if we Tab to the container or a previously focused node can't be focused again after a tree operation (e.g. a focused node has been deleted).
