video capture showing digikam's light table with unsynchronised control panning areas

SUMMARY
Using the light table in "Synchronise" mode with zoomed images, the not "active" panning control window is not synchronised with the movement of the other "active" window pane

STEPS TO REPRODUCE
1. Select 2 or more images with same size & aspect ratio, and open the Light Table
2. Use "Synchronise" mode with an image in each pane
3. Zoom more than "Fit to window" percentage
4. Move either left or right pane panning control area in its bottom right corner

OBSERVED RESULT
Panning control zoomed area moves normally in the selected pane, but remains static in the other pane

EXPECTED RESULT
Panning control zoomed areas should move the same in both panes, as main images do.
