Went ahead and changed post and topic highlights to CSS:

If this change gets merged, this will help your use case. Adding some CSS like this:

@keyframes background-fade-highlight {
  0% {
    background-color: gold; //new color!
  }
  100% {
    background-color: transparent;
  }
}

will be enough.
