`Unresolved function or method set()` error when Writable type explicitly set

[btakita]

Unresolved function or method set() error when store type is explicitly declared.

<script lang="ts">
import { writable } from 'svelte/store'
import type { Writable } from 'svelte/store'
const name:Writable<string> = writable('')
let my_name:string
$: name.set(my_name)
</script>

Adding node_modules to the Idea Libraries fixed the issue.
