 The hierarchy of widgets when QtWebEngine is involved looks like this:
 
 - qutebrowser has a `WebEngineTab` object, which is its abstraction over QtWebKit/QtWebEngine.
-- The `WebEngineTab` has a `_widget` attribute, which is the https://doc.qt.io/qt-5/qwebengineview.html[QWebEngineView]
-- That view has a https://doc.qt.io/qt-5/qwebenginepage.html[QWebEnginePage] for everything which doesn't require rendering.
-- The view also has a layout with exactly one element (which also is its `focusProxy()`)
-- That element is the  https://code.qt.io/cgit/qt/qtwebengine.git/tree/src/webenginewidgets/render_widget_host_view_qt_delegate_widget.cpp[RenderWidgetHostViewQtDelegateWidget] (it inherits https://doc.qt.io/qt-5/qquickwidget.html[QQuickWidget]) - also often referred to as RWHV or RWHVQDW. It can be obtained via `sip.cast(tab._widget.focusProxy(), QQuickWidget)`.
-- Calling `rootObject()` on that gives us the https://doc.qt.io/qt-5/qquickitem.html[QQuickItem] where Chromium renders into (?). With it, we can do things like `.setRotation(20)`.
