I don't want to pretend that I know anything about what is going on under the hood, but I think you mentioned a method "Link::VisitedQueryFinished" that forces the style change no matter what. But maybe this method isn't even called? 

Look at the below code from BaseHistory::RegisterVisitedCallback: 
```
=======================================================================
  // If this link has already been queried and we should notify, do so now.
  switch (links->mStatus) {
    case VisitedStatus::Unknown:
      break;
    case VisitedStatus::Unvisited:
      if (!StaticPrefs::layout_css_notify_of_unvisited()) {
        break;
      }
      [[fallthrough]];
    case VisitedStatus::Visited:
      aLink->VisitedQueryFinished(links->mStatus == VisitedStatus::Visited);
      break;
=====================================================================
```

It looks like some check is performed even before the "VisitedQueryFinished" is being run. So if the browser assumes the link is unvisited on this stage - it will not go deeper. Hence - will not reload styles.
