Right clicking a launcher sometimes crashes the panel

I've experienced this issue repeatedly. After adding a program to the panel using the whiskermenu's Add to Panel dialog button, it adds the launcher at the end of the panel. Sometimes when I try to right-click that launcher item to move it the dialog that's supposed to contain the Move button pops up completely empty and the whole panel freezes (empty popup dialog won't go away and all other items on the panel are irresponsive), so I have to run xfce4-panel -r to get it working again. NOTE: I have my panel docked at the top of the screen.

Attaching screenshot showing how it looks vs how it's supposed to look and the logs I got replicating this behavior running xfce4-panel through the terminal.
