Behaviour of "runAfter" for a Task that runs after a Task with Condition

[afrittoli]

Expected Behavior

I would like to have a way in Tekton to easily express the following dependency between Tasks in a pipeline: The 2nd task should run only after the 1st one was executed successfully or if the 1st one was skipped because of a condition.

Actual Behavior

If the 1st task is skipped because the condition is not met, the 2nd task is not executed at all.

Steps to Reproduce the Problem

1. Create a pipeline like similar to this:

apiVersion: tekton.dev/v1alpha1
kind: Pipeline
metadata:
  name: two-tasks-one-condition
spec:
  tasks:
  - name: conditional-task
    taskRef:
      name: task1
    conditions:
      - conditionRef: always-fail
  - name: run-if-1-or-1-skipped
    taskRef:
      name: task2
    runAfter:
      - conditional-task

2. Run the pipeline through a PipelineRun
3. task2 is not executed

Additional Info

In the example pipeline I used runAfter but I believe the behaviour would be the same if the dependency was introduced using from on a resource.

This is a feature request that looks like a duplicate of #1023

I'm going to close this out though I like the description here so I copied the Steps to Reproduce the Problem section over to #1023 👼
