Instead of one rule, make two:

     {   match = '\b(window)\.(this|parent)\b';
         captures = {
             1 = { name = 'support.class.js'; };
             2 = { name = 'variable.language.this-or-parent.js'; };
         };
     },
     {   name = 'variable.language.js';
         match = '\b(super|this|parent)\b';
     }

The first one explicitly matches window.this and window.parent. This  
and parent is still marked up as variable.language, so with no theme  
modifications, it will show the same.

But you can now style all but window.(this|parent) using a scope  
selector of:

     variable.language - variable.language.this-or-parent

Likewise you can style just window.(this|parent) with:

     variable.language.this-or-parent
