Dialog resize issue

Problem/Motivation

Discovered an issue in Claro (in Drupal 9.1) when you try to resize a dialog.
The dialog would disappear.
I also tested this on 8.9.10 and there the problem seems not to exist.

Steps to reproduce

1. Go to admin/structure/block/manage/claro_page_title
2. Click on "Browse available tokens."
3. Try to resize dialog

Note: When I override

core/drupal.dialog:
   - claro/claro.drupal.dialog

with

core/drupal.dialog:
    - seven/seven.drupal.dialog

the problem is solved. So needs to happen somewhere in the claro.drupal.dialog
