This implementation is some-what complete, with the most common missing /broken feature being opening pages in new tabs using the "_blank" target. This is currently broken due to 2 reasons: - We currently always claim the Window does not have transient activation, as we do not track the transient activation timestamp yet. This means that all such window.open calls are detected as pop-ups, and as such they are blocked. This can be easily bypassed by unchecking the 'Block Pop-ups' checkbox in the debug menu. - There is currently no mechanism for the WebContent process to request a new tab to be created by the Browser process, and as such the call to BrowsingContext::choose_a_browsing_context does not actually open another tab.
