Wine 9.16 console output

The Draggable test in the Chromium Embedded Framework sample application allows
the application itself to be moved when dragging inside a supplied red box.

Under Windows 10 this works as expected. Under Wine 9.16 this has no effect.

$ wine cefclient.exe --url=https://tests/draggable

Nothing new is printed in the console while testing this.
