Slideshow Shuffle not working when opening from Nemo

[Stabington]

Xviewer 3.0.2
Linux Mint 20.2 Cinnamon

As the title says, the Slideshow Shuffle plugin does not work when I open an image through Nemo.

After inspecting the process, it seems to open every file in the folder like:
xviewer ./file1 ./file2 ./file3 ...
I'm guessing it's doing that to account for different sorting options in Nemo.

Opening a single image through the terminal works.
