Describe the bug
when step observe controller detects the state that should be reported as CloudEvent, emit it and mark that has been actually "reported" in the metadata.annotation&PATCH it. However, 50% ratio the controller cannot get latest info with latest annotation from the TaskRun informer, so it cannot manage event emission status.
To Reproduce
apiVersion: tekton.dev/v1beta1
kind: Task
metadata:
name: hello1
spec:
steps:
- name: hello1
image: ubuntu
command:
- sleep
args:
- "15"
- name: hello2
image: ubuntu
command:
- sleep
args:
- "10 && exit 111"
- name: hello3
image: ubuntu
command:
- echo
args:
- "Hello World! ver 2"
tkn task start hello1
started
emission for step hello1
