How to set output rendering to Plain Text for errors?

Question

I run pwsh scripts in a CI pipeline. I use $PSStyle.OutputRendering = 'PlainText' to ensure the results are returned in plain text. This works for general output, however, for some reason it isn't applying to errors thrown:

> throw "Some error"
[31;1mException: [0m
[31;1m[36;1mLine |[0m
[31;1m[36;1m[36;1m  17 | [0m [36;1mthrow "Some error"[0m
[31;1m[36;1m[36;1m[0m[36;1m[0m[36;1m     | [31;1m ~~~~~~~~~~~~~~~~~~[0m
[31;1m[36;1m[36;1m[0m[36;1m[0m[36;1m[31;1m[31;1m[36;1m     | [31;1mSome error[0m

How do I get errors to be rendered as plain text as well?

For context, I'm running this in OpenShift pipelines (Tekton), here is the entirety of the TaskRun code:

apiVersion: tekton.dev/v1beta1
kind: TaskRun
metadata:
  name: test-output-rendering
spec:
  taskSpec:
    steps:
      - image: mcr.microsoft.com/powershell
        script: |
          #!/usr/bin/env pwsh

          echo '> $PSStyle.OutputRendering = PlainText'
          $PSStyle.OutputRendering = 'PlainText'
          echo '> throw "Some error"'
          throw "Some error"

As an example, the OutputRendering setting is working correctly for normal output:

- image: mcr.microsoft.com/powershell
  script: |
    #!/usr/bin/env pwsh

    echo '> Get-Item . | Format-List'
    Get-Item . | Format-List
    echo '> $PSStyle.OutputRendering = PlainText'
    $PSStyle.OutputRendering = 'PlainText'
    echo '> Get-Item . | Format-List'
    Get-Item . | Format-List

> Get-Item . | Format-List
