<p>The look of the description of the custom log message textarea is a bit misleading. It looks like a text field, which made me think if I need to write there anything, but then realized it is just a text.</p>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>Change the #description to a #placeholder in the form element and it should solve this problem. Changes could be made in CSS as well, but it's easier just to change to a placeholder and it also makes sense.</p>
<p>Before: (description property)<br>
