Blue checkbox styling is broken in Cornerstone on sites upgraded to WordPress 7.0

We have noticed that the blue styling for checked inputs is missing when adding text to a link. In the “Link options” section, the option is actually checked, but without the blue highlight, it appears unchecked.

However, when creating a new post using WordPress default posts and linking the text there, the blue styling works correctly, and the checked and unchecked states are displayed as expected.

Did a bit of digging and noticed that CSS variable --wp-admin-theme-color is undefined in /wp-admin/css/forms.min.css?ver=7.0 , causing the checkbox to lose its blue colour/styling in the admin UI.

Working vs Not Working:

  • Working - /wp-admin/css/colors/modern/colors.min.css?ver=7.0 — resolves to #3858e9
  • Not working - /wp-admin/css/forms.min.css?ver=7.0 — --wp-admin-theme-color is not defined

Hi Support, this is also happening to us too. Exactly the same problem reported above.
Please see video in secure note.
This is happening on three different sites, all using the Pro theme and WP 7.0.
Please advise how this can be fixed.
