"Instrument ordering" menu in Instruments Panel doesn't update instrument ordering

Describe the bug
The "instrument ordering" menu (as seen in the screenshot) doesn't change the instrument order when you choose a new one, unlike if you go to "Add" and change it from here. It does not display the current order as "customized" if it has been customized either. It does however change the brackets.

To Reproduce
Steps to reproduce the behavior:

1. Open a score with a lot of instruments, like one for orchestra
2. Open said menu
3. Try to choose a different order
4. See that only the brackets change and not the order
5. You can try to put a random order and put the order in the menu to Orchestral, it won't do anything either.

Expected behavior
It should change the order of the instruments, the same way the "Add" menu does. It should also say "customized" if that's the case.

Platform information

• OS: Windows 10

Additional context
The "Add" menu should be renamed to "Add & Edit" or something like that in my opinion, since I didn't think to look there at all to change the order which made me find the bug
