Changing Value Display Format to Separate Window for QImage doesn't work

When changing Value Display Format to Separate Window for QImage and then debugging code that has QImages, windows are not shown for those images. This used to work in previous versions.

The place I encountered this in was a test, but it can be reproduced with e.g.

QImage generatedImage(QSize(100, 100), QImage::Format_ARGB32);
generatedImage.fill(Qt::red);
