Bug 320813 Minimized stacks are missing on restart
Run a fresh inner (no deltas) Detach the Outline view by dragging it right maximize the editor area close restart There are no minimized stacks visible If yoiu put a breakpoint in the WBWRenderer's processContents where it's restoring the trimBars before the restart you can see that there is only the one 'top' trim bar in the model, not sure where they went...I'll attach my deltas file, to my untrained eye the minimized stacks seem to be there (i.e. if you do a find on 'left(' there is a ToolControl defined).

	 * Determines whether this feature is an indirect reference to a particular object. That is, the
	 * reference refers to an object and this reference does not necessarily describe containment.
	 * <p>
	 * An example of an indirect reference would be a handler's command. The handler points to a
	 * command but the command is actually "owned" by an application in its list of commands. In
	 * this case, there is no containment involved between the handler and the command.
	 * </p>
	 * <p>
	 * Another example of an indirect reference would be a element container's active child. In this
	 * case, the element container's contains the active child in its list of children and both this
	 * listing and the active child reference is a containment feature.
