>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #3538105. --> Reported by: [phenaproxima](https://www.drupal.org/user/205645) Related to !13 >>> <h3 id="summary-problem-motivation">Problem/Motivation</h3> <p>We now have an explicit test that at least some Mercury components are compatible with XB.</p> <p>We should expand that test to ensure that <em>all</em> components are, under the right circumstances (that is, if they have fields available that they can match to), compatible with XB -- that is, they are valid and exposed as Component config entities.</p> <p>Without this, we can never be sure that Mercury actually works in XB properly.</p>
