Module format "umd" does not support top-level await. Use the "es" or "system" output formats rather.

Doesn't support UMD output?

Vite doesn't support UMD.

Vite doesn't support UMD.

Vite can output umd, but it cannot be used with top-level-await. Is there a solution?

On discord, a user said (in response to an unrelated issue):

It should work, Vite supports UMD libs. Maybe you could create a small repro and file an issue in the repo, it can be an edge case that was not yet discovered

I get a similar error:

[web-extension:manifest] Module format "iife" does not support top-level await. Use the "es" or "system" output formats rather.

Does it also not support iife? Is there more information to help me debug these errors 🙏
