"Error: 'target' is a required option" when running imported function from ``

I have a Error.svelte component which has a <script context="module"> containing a writable store and a exported 'addError' function, altering the store content.

Error.svelte

<script context="module">    import {get, writable} from "svelte/store";    let errorStore = writable([])    export function addError(error) {        let errors = get(errorStore)        errors.push(error)        errorStore.set(errors)        throw error    }</script>

App.svelte

<script>    import Error, {addError} from './Error.svelte'    import DifferentComp from './DifferentComp.svelte'</script><Error /><button on:click={() => addError(new Error('error message'))}>    addError() from App</button><DifferentComp />

DifferentComp .svelte

<script>import {addError} from './Error.svelte'</script><button on:click={() => addError(new Error('error message'))}>    addError() from DifferentComp</button>

When importing and running this function from the component works fine, but from App.svelte I get the error message "Error: 'target' is a required option"

See this REPL for a live demo

Is there a difference when importing from App.svelte to importing from another component and there's a reason for the error, or is this simply a bug?
