I would not use the Sublime Snaps. Snaps cause problems so I avoid them as much as possible on Ubuntu 18. I found that I got error messages trying to use ExportHTML.
The problem: I was using the snap version of Firefox. When I switched to the standard version of Firefox, the problem went away. I had the ppa version of ST.
Some snaps have a preferences button that you use to tweak their behaviour. You could see if such a button exists for Sublime snaps. I know that with some snaps you have to move the slider to on in order to print.
My advice is to use the Sublime ppa if you can. I don’t use Manjaro. Or use the tarball.
