The default close button (the 'X' icon in the title bar) on Drupal's core UI dialogs is not translatable. The button's accessible label, which appears as a tooltip on hover, defaults to the hardcoded jQuery UI value of "Close".
This happens because Drupal does not explicitly set the closeText option and pass it through the translation system when initializing the jQuery UI dialog widget.
Open any dialog with close button visible in language different than EN.
Let's improve drupalSettings.dialog with:
closeText: Drupal.t('Close')
