If anyone is super motivated to tackle this I can try to help out, I have many other higher priority bugs like proper TS support, releasing Test Utils v2, etc, so I was not able to tackle this.

As far as I can see it’s (mostly) working ok for SFCs? Is this just for non sfc components? Is the main use case JSX/TSX?
