Describe the Bug

Given ./content/one.astro:

---
---

<div>TEST</div>

In Astro 5.18.1, all three patterns below trigger HMR on save of one.astro.
In Astro 6.1.10, only the first does. Furthermore, manual refresh also doesn't work in 6.1.10, it seems to be serving a cached result.

Pattern 1: static import used directly in template. Works on 5.18.1 and 6.1.10

---
import Content from './content/one.astro'
export function getStaticPaths() {
  return [{ params: { slug: 'one' } }]
}
---

<Content />

Pattern 2: static import passed as a prop via getStaticPaths. Works on 5.18.1, does NOT work on 6.1.10

---
import OneContent from './content/one.astro'

export function getStaticPaths() {
  return [{ params: { slug: 'one' }, props: { Content: OneContent } }]
}

const { Content } = Astro.props
---

<Content />

Pattern 3: dynamic import resolved at request time. Works on 5.18.1, does NOT work on 6.1.10

---
export function getStaticPaths() {
  return [{ params: { slug: 'one' } }, { params: { slug: 'two' } }]
}
const { slug } = Astro.params
const { default: Content } = await import(`./content/${slug}.astro`)
---

<Content />

This all may be related to #16342, #16000, #15983

What's the expected result?

Dynamic imports should work in Astro 6 as they previously worked in Astro 5.
