QLabel does not size properly for a movie with @2x image loaded

I loaded my file called "whatever@2x.gif" into QMovie, then set this as the movie on a QLabel.

The movie is displayed correctly respecting the devicePixelRatio == 2.0, but the QLabel is twice as big as it needs to be. There's empty space around the actual animation.

If I check my movie.currentPixmap().devicePixelRatio() it is correct.

I see in qlabel.cpp that QLabelPrivate::sizeForWidth() does not use the devicePixelRatio of the movie frames as it does for a pixmap set directly on the label.

Workaround: set the label to have a fixed size of movie.currentPixmap().size() / movie.currentPixmap().devicePixelRatio().
