Description

This PR updates the Brave Ads code to include additional user data when handling page land events. Specifically, it adds an is_error_page boolean flag to the NotifyTabDidChange method to indicate if the page load resulted in an error. This flag replaces the previous http_response_status_code parameter. The user data sent with page land events now includes an "errorPage" key if is_error_page is true.

Security Hotspots

None identified. The changes do not introduce any new untrusted input and the page error status seems to be determined securely on the browser side before being passed to the Brave Ads code.
