Steps to reproduce

Just create 2 components written in JSX and try to use slot

What is expected?

The linked app should display "Bar"

What is actually happening?

The slot is not computed, and the JSX element "slot" can be spot when you inspect the source code

I'm sorry, I never managed to make JSX work with Vue next on any Fiddle website :(

Theres no <slot> element in JSX. Just run the slot function

{ slot.default() }
