Windows does not use `DejaVuSansMono` font

[higaski]

For some reason loading DejaVuSansMono works, but using it doesn't?

if (QFontDatabase::addApplicationFont(":/fonts/DejaVuSansMono.ttf") == -1)
  return -1;
QFont font{"DejaVuSansMono"};
font.setPointSize(10);
font.setStyleHint(QFont::Monospace);
app.setFont(font);

Now the [docs] say that one should not use setFont together with stylesheets, however it also doesn't work if no stylesheet whatsoever is applied...
