QActiveX wrong rendered size in High DPI

The area painted by ActiveX controls inside QAxWidgets remain in non scaled coordinates.

The attached code opens two windows one with Media Player control and one with Web Browser control. Try resizing the Media Player window to notice the effect. The Web Browser control already gets rendered with the bug behavior.

This is also happens in Qt 5.6 with
QApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
