Would it be possible to cherry-pick this commit and add it to the
patches field of entt's origin?

I'm inexperienced with cherry-picking. I will try to do it, but the
maintainer mentioned another release might come soon, so if that happens
before I get to figure this out, I will come back with a recipe for the
new version which will contain the fixed tests too.

Cheers.

The new release indeed came and after a discussion with the maintainer I
managed to get all the tests running too. I'm attaching the a new patch
with the lastest version to this email.

Thanks!  I've applied some small cosmetic changes, moved the package to
game-development.scm (where I feel it would fit better) and pushed it
to master.
