Handle more complex ContentSlot

[Atinux]

Ex:

• https://github.com/nuxt-themes/elements/blob/dev/components/globals/List.vue#L46
• https://github.com/Atinux/content-wind/blob/main/components/content/List.vue#L17

@Atinux ; what do you think would be the best way to resolve this?

h('span', h(resolveComponent('ContentSlot'), { use: () => item }))

There is no real "proper" way to parse such usage.. except maybe if I only detect h(resolveComponent('ContentSlot')) as default slot in response?

That would kind of mean we only do support default slots for such usage?

If that's fine, I can make that change.
