Focus does not seem to erase your history in a way you may expect. Try this on Android:

- Erase your history.

- Go to HN, click any link you haven't clicked before.

- Wait for it to load.

- Erase your history. Make sure you see the notification "Your browsing history has been erased".

- Go to HN again, and see the link you've just clicked still highlighted as 'visited'.
