Renaming a control block removes subscriptions

[danyill]

Describe the bug

When a control block name is edited in OpenSCD, subscriptions are invalidated.

To Reproduce

Steps to reproduce the behavior:

1. Carry out subscriptions for GOOSE or Sampled Values.
2. Edit a control block (e.g. from the Substation screen by clicking on the (R) or (S))
3. Rename the control block
4. Go to the subscription editor
5. See no count against the subscriptions.

Expected behavior

Renaming a control block results in the srcCBName of subscribed ExtRef elements being updated.

Screenshots

1. Subscription added:

   

2. Control block renamed:

   

3. After clicking Save, the subscriptions are lost:

   

4. I tested this with a GSEControl element but the same is true for a SampledValueControl

Additional context

Here's the file I used for demonstration.

The agreed solution was that the wizard takes care of the renaming of references.
If the use-case comes up often we may extract it out to an SCL library
