[6.x] Adding set in nested Replicator causes "Something went wrong"

[o1y]

Bug description

When working with a nested Replicator field, attempting to add a new set inside the nested Replicator causes the publish form to crash with a generic "Something went wrong" error.

This might be related to overlapping set handles, but I haven’t been able to fully confirm this yet.

I've attached the relevant replicator / blueprint configuration to make the issue reproducible.

How to reproduce

1. Add the provided blueprint / fieldset configuration
2. Add an entry using this blueprint
3. Try to add a new set inside the nested Replicator
