World Outliner: Selecting Folder fails (needs to be clicked twice)

I've investigated the issue and it is related to TypedElementSelection sending out end of frame selection change events.

WorldOutliner when it is the source of a selection change does so inside a reentrant scoped flag so that it doesn't react to the selection change events in that scope.

It seems like the new TypedElement selection defers some events to end of frame and breaks that functionality causing the Outliner to clear its selection on one of those end of frame events.

Create a new map

Create a Folder in the World Outliner

Select an Actor

Select the Folder

Folder gets deselected right a way (It shouldn't)
