Shortcut when using multiple instances break after darktable restart

Is there an existing issue for this?

• I checked and did not find my issue in the already reported ones

Describe the bug

Shortcuts get broken after DT reset - I think this happens if theres a "first" option in the effect collumn, as well as a "first" option in the instance collumn. If I then set a shortcut that should apply to "first" instance, after a restart moves the first to effect.... They share the same name, whatever loads/saves the shortcut gets confused..?

Steps to reproduce

• Go to settings
• Set a shortcut, for example here illuminant, since it has a dropdown menu and the first options - that breaks consistently, popups do too... anything that has a "first" in effect i would guess, or just an effect+instance named the same.

• Shortcut works as intended for this launch

• Restart darktable

• Check settings: the "first" has moved into the effect collumn, shortcut is now broken...

Expected behavior

Keep the settings as set

darktable version

5.7.0+923.g6a2f19f4e3, though I feel like this has been an issue on earlier versions too, its just that my workflow now requires to have more instances of modules on and this makes shorcuts useless.

What OS are you using?

Linux

What is the version of your OS?

CachyOS

Are you using OpenCL GPU in darktable?

Yes

Reproduce the issue in darktable 5.7.0+923.g6a2f19f4e3 by assigning a shortcut to the first instance of Illuminant, then restart and inspect the shortcut settings. Trace the shortcut save/load handling for effect and instance names that are both "first"; done means the assignment remains associated with the instance after restarting.
