Steps to Reproduce

Upgrade mithril from 2.2.2 to 2.2.3+

Expected Behavior

No errors/breaking of rendering.

Observed Behavior

I see these errors on a bunch of my tests after upgrading from 2.2.2 to 2.2.3 (problem still exists in 2.2.10), and it breaks rendering. This does NOT happen at all on 2.2.2.

This could be a happy-dom issue, but I'd love to be able to provide a reproducible thing that doesn't involve a ton of libraries. Is there any logging I could add to render.js or domFor.js to narrow down the issue or what el it's acting on?

DOMException: Failed to execute 'insertBefore' on 'Node'

It seems there was an issue a while ago regarding insertBefore of happydom.
I don't know if it's the same issue, though.
