1843308 - Take into account openers in BounceTrackingState::OnStartNavigation

Status: RESOLVED FIXED

(Core :: Privacy: Anti-Tracking, task, P2)

Description

[Emma Zühlcke [:emz]]

When a navigation is started as the result of opening a new tab or window, e.g. by link click or by window.open call we need to ensure the BounceTrackingRecord is still properly tracked across opener relationship.
See https://github.com/privacycg/nav-tracking-mitigations/issues/50 for details.

Note: This includes the case where the current navigation was initiated by another navigable, e.g. when opening a link in a new tab. In this case, sourceDocument is set to the opener Document, and the new bounce tracking record has its initial host set to the opener host. This ensures that trackers opened in new tabs are detected as distinct from the initial host in the new bounce tracking record.
