PyQt5 bug in font settings

I believe I found a bug in PyQt5 (or QT?) , surfacing only under 
Windows, perhaps only Win10

The problem: A font may be set, and confirmed by PyQt5 to be in use, yet 
the actual font is a completely different one. I noticed this when I 
defined a fixed width font, but became a proportional font, despite 
PyQt5 telling it is Courier New.
