[drupalImage] Image links fail to update when using Full HTML

Could you please convert your manual steps to reproduce (thanks!) into a test instead? 🙏

\Drupal\Tests\ckeditor5\FunctionalJavascript\ImageTestBase::testLinkability() actually already tests this for both Basic HTML and Full HTML:

  public function providerLinkability(): array {
    return [
      'BLOCK image, restricted' => ['block', FALSE],
      'BLOCK image, unrestricted' => ['block', TRUE],
      'INLINE image, restricted' => ['inline', FALSE],
      'INLINE image, unrestricted' => ['inline', TRUE],
    ];
  }

("unrestricted" = Full HTML, "restricted" = Basic HTML)

That is testing with:

    // Fill in link form balloon's <input> and hit "Save".
    $url_input->setValue('http://www.drupal.org/association');
    $balloon->pressButton('Save');

What you're describing is editing a link. The test is currently only adding/removing a link.
