Dynamically named items (e.g. Storage Drawer keyring) maintain a static name in the tooltip of the morph tool

[Jack-McKalling]

The keyring of Storage Drawers supports adding and removing keys at any time, and it shows the currently selected key in its name between brackets. With this keyring in the tool, the morphing tool doesn't display the updated name of the selected item when its name changes.

E.g. when you add a key (e.g. "Drawer Key") to a blank keyring ("Keyring"), the keyring will change name to display "Keyring (Drawer Key)". If you then add another key ("Quantify Key") and switch to select that one, it renames to "Keyring (Quantify Key"). Each shift-right-click with it will swap between the names. But when the keyring is added to the morphing tool, the name of the keyring will always stay the same as it was when added, regardless of what key is currently selected or even removed from it.
