E0158: A tag leaves out a required field

A component's field tagged vuka:"required" is filled at every tag that uses the component: a slot by <slot:name>…</slot:name> (or the attribute), Children by content between the tags, any other prop by its attribute. A repeated slot's element struct may require fields too, filled on each <slot:x>.

Wrong

<script lang="go">
package pages

import "example.com/app/components"

// components.Card declares Header ui.Node `vuka:"required"`.
type Orders struct{}
</script>

<components.Card>
  <p>No orders yet.</p>
</components.Card>

<components.Card>
  <slot:header><h2>Orders</h2></slot:header>
  <p>No orders yet.</p>
