Additional modal support

Perfect for everything, 2 missing points:
- when I select a media in the media library, then if I reopen the media library, there is "1 item selected" indicated while there is no media selected. In Core https://git.drupalcode.org/project/drupal/-/blob/11.x/core/modules/media..., Media Library listens to dialog:afterclose to reset the counter.
- for node preview modal cancel button, like you mentioned in private, I will check for a core issue for that.

Merged. Thanks!
