Previously, failed task rus did not emit results, now they do but the UI still shows "No TaskRun results available due to failure" even though task run's status contains a result.
    

4.14.3
    

Always with a task run producing a result but failing afterwards
    

    1. Create the pipelinerun below
    2. have a look on its task run
    

apiVersion: tekton.dev/v1
kind: Pipeline
metadata:
  name: hello-pipeline
spec:
  tasks:
  - name: hello
    taskSpec:
      results:
      - name: greeting1
      steps:
      - name: greet
        image: registry.access.redhat.com/ubi8/ubi-minimal
        script: |
          #!/usr/bin/env bash
          set -e
          echo -n "Hello World!" | tee $(results.greeting1.path)
          exit 1
  results:
  - name: greeting2
    value: $(tasks.hello.results.greeting1)
    

No results in UI
    

One result should be displayed even though task run failed
