--- Comment #12 from David Faure <fa...@kde.org> ---
The deleted focus-widget had a focus proxy,
QtWebEngineCore::RenderWidgetHostViewQtDelegateWidget
But QApplicationPrivate::focus_widget is the WebEngineView, not its focus
proxy.
Due to that, QWidget::hasFocus() [which follows to the focus proxy] on both
widgets is false, so QWidget::clearFocus() doesn't call
QApplicationPrivate::setFocusWidget(0) for either of them.
At the time of the initial QApplicationPrivate::setFocusWidget (which happens
when konqueror calls part->widget()->setFocus()), the WebEngineView
doesn't have a focus proxy yet.
That happens later, in QWebEngineViewPrivate::widgetChanged.
QWidget::setFocusProxy doesn't update the app focus_proxy, that seems to be
what's missing. No idea how it ever worked before though.
Reproduced with unittest for Qt. Made a Qt fix.
