<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>When adding a workflow state (using the contrib <a href="https://www.drupal.org/project/workflow">Workflow module</a>) we get a WSOD (see below).</p>
<p>I suspect that this has to do with how the Workflow States form (`workflow_state_form`) is structured. While we generally handle forms that contain multiple configs gracefully, this one might be an exception.</p>

<h4 id="summary-steps-reproduce">Steps to reproduce</h4>
<ol>
<li>Enable Config Enforce Devel</li>
<li>Create a workflow</li>
<li>Create a workflow state</li>
<li>Enforce the workflow state</li>
<li>Add a second workflow state</li>
<li>Observe the WSOD (see above)</li>
</ol>
<p>I don't recall if this occurs upon adding the first workflow state. But it definitely doe on subsequent ones.</p>
