Deleting items does not update instrumentation #59
Description
Reproduce:
- On a blank page, create 3 sections
- Delete the middle section
- Delete the last section, previously section 3, now section 2
- It will try to delete section 3, which it doesn't find anymore, since the ue service now refers to this as section 2 when it re-pulls the instrumented document
- Reload the page, and deleting section 2 works again
