Auto merge of #17889 - chenpighead:fix-transition-visited, r=hiro

stylo: remove bogus optimization check in replace_rules() for visited styles.

We skipped updating the rule nodes for visited rules during animation-only restyle.
However, this causes isseus that visited style overrides animation styles on visited element.
So, it turns out that we should update the visited rules even during animation-only restyle.
