[SOLVED] Wrong path and missing dependencies when integrating @kie-tools/kie-editors-standalone into Vue 3/Vite app

I'm building a Vue 3/TypeScript/Vite app, where one page is dedicated to showing a read-only DMN editor with a rules file. To this end, I'm using @kie-tools/kie-editors-standalone. Here is the Vue file in question:

<template>
  <h1>Rules</h1>

  <div id="dmn-editor-container"></div>

  <ErrorDialogueBox ref="errorDialogueBox"/>
</template>

<script setup lang="ts">
import {onMounted, ref} from "vue";
import axios from "axios";
import {useAppConfigStore} from "@/stores/config.store";
import {storeToRefs} from "pinia";
import {useAuthStore} from "@/stores/auth.store";
import * as DmnEditor from "@kogito-tooling/kie-editors-standalone/dist/dmn";
import ErrorDialogueBox from "@/components/ErrorDialogueBox.vue";
import type {ApiError} from "@/api";

const {token} = storeToRefs(useAuthStore());
const {backendApi} = useAppConfigStore();

const webApi = backendApi();

const errorDialogueBox = ref<InstanceType<typeof ErrorDialogueBox> | null>(null);
const showError = (title: string, message: string) => errorDialogueBox.value?.showError(title, message);

onMounted(() => {
  webApi.get("/rules",
            {
              headers: {Authorization: `Bearer ${token.value}`},
            })
        .then(result => {
          const xml = result.data;
          const element = document.getElementById("dmn-editor-container");
          if (element) {
            DmnEditor.open({
              container: element,
              initialContent: Promise.resolve(xml),
              readOnly: true
            });
          } else {
            showError("DOM error", "Could not find dmn-editor-container element");
          }
        })
        .catch(error => {
          if (axios.isAxiosError(error)) {
            const apiError = error.response?.data as ApiError;
            console.log(apiError);
            showError("Could not fetch details", apiError.message || error.message);
          } else {
            console.log(error);
            showError("Could not fetch details", error as string);
          }
        });
});
</script>

<style scoped>
#dmn-editor-container {
  height: 70vh;
}
</style>

The diagram actually renders correctly, but the decision tables are all empty when clicking the pencil icon. There are also a lot of 404 errors in the console:

(Edited for clarity; over 1000 lines of error messages aren't very useful.)

So what appears to be going wrong:

It attempts to load from the document root / instead of /node_modules.
None of these are to be found anywhere in the library's package.json as a dependency.

As mentioned, I used Vite, whereas the library uses Webpack. I don't know if that makes a difference.

Any help is greatly appreciated.

Edit: updated to @kie-tools/kie-editors-standalone instead of @kogito-tooling/kie-editors-standalone, but that doesn't make a difference.
