Binding this in inline Vue components to access all frontmatter

[Actimia]

I've started migrating my app to nuxt3, and before I could write <ThingComponent :item='this' /> in a .md file to have access to the full frontmatter in the component. This does not seem to work in nuxt3, and I am instead getting the string 'this' bound. I can bind individual parts of the frontmatter fine, but I would like the whole thing :) Any clues?
