public bool allow_top_navigation_to_data_urls { get; set construct; }
Whether or not the top frame is allowed to navigate to data URLs.
It is disabled by default due to the risk it poses when loading untrusted URLs, with data URLs being used in scamming and phishing attacks. In contrast, a scenario where it could be enabled could be an app that embeds a WebView and you have control of the pages being show instead of a generic browser.
