Effect: Image navigation thumbnail error on amimated GIF images when zoomed in.
By default, zooming in an animated GIF won't display the image navigation thumbnail in the bottom-right corner of the window, not sure if that's already a bug but if you first open a non-animated image and then move to an animated GIF and zoom it in, the image navigation thumbnail will appear displaying just a black preview.
To reproduce:
1. Open a non-animated image.
2. Use the Left/Right arrows to move to an animated GIF.
3. Zoom in.
Actual behaviour (bug): The image navigation thumbnail appears with a black preview
Expected behaviour: The image navigation thumbnail to display the actual preview of the current image, perhaps as a not animated preview of the first frame in the GIF?.
