Bugfix #7294:

When resizing an Outliner window, the contents would eventually get 'pushed out of view' when shrinking the view. 

I've added a bit of a 'hack', which will ensure that this doesn't happen, by forcing the view to look at the left-side of the outliner tree, when the width of the outliner window decreses due to resizing.
