1. Navigate to Configuration -> Hosts -> Items.
2. Find a templated item and click to edit it.
3. Observe that your location the chosen host.
4. Click on parent item.
5. Observe that your location is now the template.
6. Click update.
7. Observe that your location is back to the host.

Try to do this for other objects like triggers or graphs. It works differently. For all other objects like triggers, graphs, LLD rules, web scenarios and other, after updating the parent, location remains the template. It does not redirect back to host.

In trunk both items and triggers redirect back to host. But still graphs, LLD rules, web scenarios and others don't.

Something should be done about this. At least make it consistent.
