Safari not working right

There is a blank placeholder for a page element named "AdThrive_Sidebar ... "

Its name implies the placeholder is intended for an advertisement whose content is missing.

Brave incorporates native ad-blocking features, so it can be assumed Brave is ignoring that page element whereas Safari is including it. Which one of those page rendering behaviors is "correct" is a matter of perspective. Presumably, an advertiser seeking to capitalize on clickthrough revenue would object to the way Brave renders web pages.

So do I. Brave continues to impress.
