An object can be targeted by a driver that reads its `hide_viewport` or `hide_render` property. The existence of such a driver will create a relation between the 'sync base flags' depsgrpah node, and the datablock containing the driver. When the object is hidden, however, it has no base, and thus it had no 'sync base flags' depsgraph node. To support such a driver, that depsgraph node is now always added, but for hidden objects it will just be a no-op. If the node is not used by anything, it will be automatically disconnected and have a negligible effect on performance.
