SUMMARY
Zoom of multiple images opened in the same window by Ctrl++ or Ctrl+- or Ctrl+MouseWheel is broken.
Works under X11 and Wayland.

STEPS TO REPRODUCE
1. Open Gwenview with an image
2. Go to "Browse" tab
3. Move to simular picture with the same resolution
4. Press "+" icon
5. Go to "View" tab
6. Enable "Synchronize" option below
6. Select any image and try to zoom it

OBSERVED RESULT
Zoom is broken although drag and move (LeftClick) of pictures is fine.

EXPECTED RESULT
I want it to work properly. And if images have different resoluion then to zoom into point proportionally, as if i'd zoomed into 70% of width of first image then it must zoom into 70% of second image too. Same with height.
