MJML plugin no longer working

[rogueturnip]

Hi!

I'm trying to get the MJML plugin working and it seems that the "Invalid Target Position" bug is popping up.

I'm using GrapesJS 0.21.5 and mjml 1.0.5.

This is using @grapesjs/react as a wrapper and everything works fine once the mjml plugin is removed.

I tested it here https://grapesjs-react-default-ui-etee4r.stackblitz.io

thanks!
