I'm using v4.0.0 of the Restore action, and I've noticed consistently that if there's a cache miss, that the step of the workflow errors, but it does not fail the job/workflow

I get this all the time
Error: Failed to restore cache entry. Exiting as fail-on-cache-miss is set.

But then the job proceeds just fine and after it's done I see a checkmark in the "workflow summary" page for that job.

I would expect that it should fail the job right at that step as soon as the cache miss occurs

Reproduce the cache miss with the v4.0.0 Restore action and fail-on-cache-miss enabled in a GitHub Actions workflow. Inspect the Restore action's error handling and verify that a cache miss causes the workflow job to fail at that step, rather than continuing to a successful checkmark.
