Problem with adding programs to panel. Video demonstration link.
Hard to describe, there is an annoying bug that whenever I want to add a program to the panel, it first adds firefox, and then thunar, and after that the program I want.
Please watch my 44 second silent video demonstration. I hope someone can tell me what the problem is and how to fix it. (I have the same problem on three computers)
Distro: Linux Mint 21.3 Virginia base: Ubuntu 22.04 jammy Desktop: Xfce 4.18.1 Whisker Menu: xfce4-whiskermenu-plugin 2.7.2-1~bpo22.04
Out of the box, it doesn't seem to have the bug, but after a while the bug shows up.
