Sushi doesnt work for many file types (gnome 42)

After updating to G.42 I noticed that Sushi (pressing space to preview files) doesn’t work for .css .js .php & many other formats that used to work.
The error shown is r.mineTypes is undefined

Looks like this bug has been fixed in Sushi, ~ do we just wait for it to filter down or can I do something?

Yes, this package comes from arch: Arch Linux - sushi 41.2-1 (x86_64)
It is not flagged out of date. There might not be a new release out yet: Branches · GNOME / sushi · GitLab to package.
