Link dialog cannot be closed

The MR and attached patch removes the override.

I haven't found another way to prevent having the click submit twice though. Contributions are welcome!

I tested a vanilla setup with 10.3.6 and 2.0.0 and can't reproduce any issues with the dialogs.

That code actually exists to disable the LinkUI close method for the ckeditor popup when a drupal modal is open. When the modal is closed, it re-binds the original so you can close the first (ckeditor) link ui popup.

Having said that, my original code for that looks pretty brittle, with a hardcoded class:

    linkUI._hideUI = () => {
      const modal = document.querySelectorAll('.ui-dialog-content');
      if (modal.length === 0) {
        _hideUIOriginal.bind(linkUI).call();
      }
    };

And maybe in your case that class does not exist? In that case the re-bind wouldnt happen explaining your issue. I would welcome a patch/MR to improve this.
