The contents of the slot will never change.

[ttdly]

I want to insert some information in the header of the document that can change with the page. And I use layout-slots to do this. But the contents of the slot will never change unless I refresh the page😢 How can I implement this feature🙏
You can see the changes I made here.

You need to use computed:

const title = computed(() => frontmatter.value.title)
