Any way to set the dark theme?

Hey,

I’ve noticed that since the last update, the frontend of my site shows me PDF.js in its light theme version. In previous versions it used to display the dark theme automatically, I don’t know why. But I liked the dark theme better.

I was wondering whether there’s a way of changing PDF.js’s theme from light to dark. I was hoping to find an option on the plugin’s settings, but it’s not there.
