<h3 id="overview">Overview</h3>
<p>It does not appear that the <code>description</code> of a prop is used in the corresponding form element.</p>
<p>Given</p>
<pre>$schema: 'https://git.drupalcode.org/project/drupal/-/raw/HEAD/core/assets/schemas/v1/metadata.schema.json'<br>name: My SDC<br>status: stable<br>group: Molecule/My SDC<br>props:<br> type: object<br> properties:<br> some_prop:<br> type: string<br> title: Some Prop<br> description: Should I show up as the textfield description?</pre><p>I rather expected <code>Should I show up as the textfield description?</code> to appear as an equivalent-ish thing to the FAPI <code>#description</code> on the corresponding form element.</p>
<h3 id="proposed-resolution">Proposed resolution</h3>
<p>Either make the form element display the <code>#description</code> or educate me on the intended use of <code>description</code> 😅.</p>
<h3 id="ui-changes">User interface changes</h3>
<p>Possibly many, depending on the outcome!<br>
