public function MediaTest::testLinkability in Drupal 10

Same name in this branch
  1. 10 core/modules/ckeditor/tests/src/FunctionalJavascript/MediaTest.php \Drupal\Tests\ckeditor\FunctionalJavascript\MediaTest::testLinkability()
  2. 10 core/modules/ckeditor5/tests/src/FunctionalJavascript/MediaTest.php \Drupal\Tests\ckeditor5\FunctionalJavascript\MediaTest::testLinkability()

Tests linkability of the media CKEditor widget.

Due to the very different HTML markup generated for the editing view and the data view, this is explicitly testing the "editingDowncast" and "dataDowncast" results. These are CKEditor 5 concepts.
