AT:

• given:
  • I have the attached process deployed transaction-mi.png
  • Multi Instance transaction cardinality is 3 (or I have a collection with three elements)
  • I have started a process instance
• when:
  • the first two multi-instance loops/transactions are completed successfully
  • the last loop/transaction has a failure and triggers a cancellation
• then:
  • Only the last multi-instance gets compensated
• expected:
  • all three multi-instances get compensated

Hint:
Here is a testcase:
https://github.com/camunda/camunda-bpm-platform/commit/32be758e4ea4fe64de75b1145cd4ce5b4f13acc2

Also test that all transactions/loops after the cancellation are canceled and not executed anymore.
