I'm pretty sure Safari on macOS has some sort of blacklisting mechanism that's preventing some of the my frequently visited websites from appearing in that list. Is there a way to disable that feature?
I have Safari 13.0.4 on macOS Catalina but I think the feature (issue) has been present perhaps for years.
