Does not fix the issue where the column needs to shrink/expand on zooming
Why is it that bugs like this are the smallest diffs?
remove needless call to FullReposition, as RequestReposition is called by it, and again only a few lines later in this function!
unsorted featuresets on new feature added to try to fix overlap bug - displayed format is now stable from first display. Difficult to test as cannot create overlap on demand
