The code updates, but the options in the list prop get removed.</p> <p>Case #2:</p> <p>Create a simple component without a list prop.</p> <p>Add a follow-up message to include a new prop of type list. The new prop gets created, but without its values/options, resulting in a red error.</p> <h3 id="proposed-resolution">Proposed resolution</h3> <p>This seems a regression of <span class="drupalorg-gitlab-issue-link drupalorg-gitlab-link-wrapper"><a href="https://git.drupalcode.org/project/canvas/-/work_items/3537620" class="drupalorg-gitlab-link">https://git.drupalcode.org/project/canvas/-/work_items/3537620</a></span> to me.
