Expected Behavior

When fanning out a Matrixed PipelineTask I expect to see the logs for all of the TaskRuns created - for example, below we are echoing platform and browser for 9 combinations that are fanned out into 9 TaskRuns from the Matrixed PipelineRun - I expect when I get the pr logs, it would show the logs for all 9 TaskRuns:
