Description
-------

`PanelView::event()` generates new events for itself and dispatches them via `QCoreApplication::sendEvent()`, which calls the handler directly. This can lead to endless recursion. This patch changes the handler to use `QCoreApplication::postEvent()` instead to enqueue the new event and dispatch it from `QEventLoop` after the current `PanelView::event()` returns.
