<p>In the repo it does also look funny, weridly enough it looks ok when being used by the editor, see svg here: <a href="https://git.drupalcode.org/project/ai/-/tree/1.1.x/modules/ai_ckeditor/icons?ref_type=heads">https://git.drupalcode.org/project/ai/-/tree/1.1.x/modules/ai_ckeditor/icons?ref_type=heads</a></p>
<p>This broke as part of this issue: <span class="drupalorg-gitlab-issue-link project-issue-status-info project-issue-status-7"><a href="https://www.drupal.org/project/ai/issues/3494281" title="Status: Closed (fixed)">#3494281: CKEditor icon when in Gin Dark mode</a></span>. Before that the preview looked good, but didn't work in Dark Theme on Gin: <a href="https://git.drupalcode.org/project/ai/-/blob/512750d0c74c23a2c665a11f0937109b2f51d7a4/modules/ai_ckeditor/icons/sparkles.svg">https://git.drupalcode.org/project/ai/-/blob/512750d0c74c23a2c665a11f0937109b2f51d7a4/modules/ai_ckeditor/icons/sparkles.svg</a></p>
