Comment (by neo2k23):

 I think i know the why.

 The admin-scheme.css uses the body element

         body.admin-color-modern {
           --wp-admin-theme-color: #3858e9;
           --wp-admin-theme-color--rgb: 56, 88, 233;
           --wp-admin-theme-color-darker-10: rgb(33.0384615385,
 68.7307692308, 230.4615384615);
           --wp-admin-theme-color-darker-10--rgb: 33.0384615385,
 68.7307692308, 230.4615384615;
           --wp-admin-theme-color-darker-20: rgb(23.6923076923,
 58.1538461538, 214.3076923077);
           --wp-admin-theme-color-darker-20--rgb: 23.6923076923,
 58.1538461538, 214.3076923077;
           --wp-admin-border-width-focus: 2px;
         }

 The popup i have has a tb_window  iframe TB_iframeContent  with a body and
 on top of that the media selector popup.  All the default scripts are
 loaded before the body after iframe TB_iframeContent

 The media selector however has somehow lost the connection between the
 body within the iframe.  so body.admin-color-modern is not applied.

 I have to add that css myself to the iframe wrapper and then it works>

 If i add

         .wp-core-ui .button-primary {
           --wp-admin-theme-color: #3858e9;
           --wp-admin-theme-color--rgb: 56, 88, 233;
           --wp-admin-theme-color-darker-10: rgb(33.0384615385,
 68.7307692308, 230.4615384615);
           --wp-admin-theme-color-darker-10--rgb: 33.0384615385,
 68.7307692308, 230.4615384615;
           --wp-admin-theme-color-darker-20: rgb(23.6923076923,
 58.1538461538, 214.3076923077);
           --wp-admin-theme-color-darker-20--rgb: 23.6923076923,
 58.1538461538, 214.3076923077;
           --wp-admin-border-width-focus: 2px;
         }

 To the theme shortcode css it works again.
