QWebEngineView - InstallEventFilter, not firing MouseMove

[maximus]

Just switched from QWebView to QWebEngine,

This signal is no longer fired when moving the mouse on the QWebEngineView, was working with QWebView:

1- webEngineView->installEventFilter(this);
2- mouse move on the View, no signal is fired

I need this signal to activate/deactivate the toolbar (location edit, button, etc.) dynamically.
Thanks
