QWebEngineDownloadItem::path uses native separators when the file already exists

The path returned by QWebEngineDownloadItem::path() contains native separators ('\' on Windows) instead of the standardized '/' used in Qt.

For instance the following code

connect(profile, &QWebEngineProfile::downloadRequested,
        this, [this](QWebEngineDownloadItem *dl) {
		qDebug() << "Download request:" << dl->path();
	});

will generate the following output

Download request: "C:\\Users\\User\\Downloads\\downloaded_file (1).ext"

while I was expecting

Download request: "C:/Users/User/Downloads/downloaded_file (1).ext"

This happens only when there is already a file with the same name in the download folder and the file must be renamed with a number.

On the first download path will be C:/Users/User/Downloads/downloaded_file.ext, but for the second download it will be C:\Users\User\Downloads\downloaded_file (1).ext.
