Previous tests results not downloaded on forked PR

We’ve recently enabled forked PRs to be able to run our CI/CD workflow. The workflow is triggered, but it fails when checking if the previous tests information is present (ok, probably we could move this step a bit earlier, but that’s another topic). And comparing with successful workflows, indeed the step where previous tests would be downloaded is missing.

Here’s a failed execution.
And here’s a successful one.

Is this not expected to work? Have we not enabled something in the settings? Is this a bug on CircleCI’s side?
