Change Details

Qt 5.13+ has a built-in PDFium-based PDF viewer enabled in QWebEngineSettings by default. There is no way to disable it at run time by the user, and leaving it "as is" changes the browser's behavior, depending on which version of Qt is installed on a target system. The built-in plugin currently has quite a limited functionality and, e.g., misses ability to download the document being viewed. This disables internal Qt's PDF viewer, keeping behavior on newer systems (with Qt 5.13+) the same as on older ones.
