If anyone can show how to build, I can write a Github action so we can get this working in CI

Sorry for the late response, some help on this subject would be appreciated because I can't really help on the iife bugs at the moment, since I didn't build the library and never work on iife build myself

Managed to reproduce this, in v4.1 iife builds are fixed, additionally, raw svelte components are also packaged.
