I don't see any playwright runs for this PR. Should they run for this PR?

[mickmister]

@hanzei It could be because the ci / plugin-ci / delivery (pull_request) job was skipped. It's possible all of the jobs in that workflow need to run/complete?

This step only runs on master or main @mickmister https://github.com/mattermost/actions-workflows/blob/main/.github/workflows/plugin-ci.yml#L78

Also workflow run events need to be commited to master first before they actually run on PRs for security reasons .
Check https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#workflow_run

Note: This event will only trigger a workflow run if the workflow file is on the default branch.

You are good to ship. I would suggest also adding an extra condition in order to check if ci workflow run was actually successful but it's fine for now

if: github.event.workflow_run.conclusion == 'success'
