System info:
Distributor ID: Ubuntu
Description: Ubuntu Jammy Jellyfish (development branch)
Release: 22.04
Codename: jammy
Mate Desktop 1.26.0
Mate Panel 1.26.2
Three displays are connected: secondary - main - secondary(below main)
See the screenshot attached.

Problem: If mate-panel orientation is set from the bottom to the left. Then you hover the mouse over the open app icon in mate-panel it shows a small window preview on the secondary display to the left

Expected behavior:
if you hover the mouse over the open app icon in the mate-panel it shows a small window preview on the main display.

@Martin
What should I change in the Control center to fix that behavior?
Or is it still a bug?

The attached screenshot shows that the window previews ( while hovering the mouse over it icons in mate-panel) are shown on the wrong display (not on the one that is set as the primary, where the actual mate-panel is).
