No, this was not sorted out for libpdfium-nojs.
In June I experienced a similar issue with package libadwaita-shortwave. I first thought that this is an issue with the AUR helper I am using (paru). So I opened an issue for it on github: https://github.com/Morganamilo/paru/issues/422
But during the discussion with the paru developer it became clear that this is an issue with how the PKGBUILD is written.
Luckily the package maintainer was listening to the suggestions from the paru developer and changed the package: https://aur.archlinux.org/packages/libadwaita-shortwave/
I did not go that far for libpdfium-nojs. I have simply put it on the IgnorePkg list.
