Bug 343445 [model] transient data does not notify
The new transient data map <String, Object> does not notify about changes and the owner contains a setTransientData(*) member. It should be more like org.eclipse.e4.ui.model.application.MContribution.getPersistedState() PW
bundles/org.eclipse.e4.ui.model.workbench/src/org/eclipse/e4/ui/model/application/impl/ApplicationElementImpl.java
setElementId(ELEMENT_ID_EDEFAULT);
				return;
			case ApplicationPackageImpl.APPLICATION_ELEMENT__TAGS:
				getTags().clear();
				return;

				return;

		super.eUnset(featureID);
