   Hello. It seems like SeaMonkey doesn't have support for the :has() CSS   
   selector, probably because it's still based on an older version of   
   Gecko. Is there a good alternative that I can use to replace :has() on   
   my own CSS to provide compatibility for SeaMonkey? Or, would this   
   feature be available some time soon?   
      
   Thanks.
