BalloonToolbar throws an error when used with MultirootEditor

[GoProduction]

📝 When attempting to import the balloon toolbar into the multiroot-editor, it will throw a TypeError of: "Cannot read properties of undefined (reading 'Symbol(emitterId)')"

Here is an image of the callstack:

The (shortened) code that I'm working with:

import { MultiRootEditor } from '@ckeditor/ckeditor5-editor-multi-root';
import { FontBackgroundColor, FontColor, FontFamily, FontSize } from '@ckeditor/ckeditor5-font';
import { BalloonToolbar } from "@ckeditor/ckeditor5-ui/src/index";

async buildEditor() {
	let toolbarConfig = await ToolbarConfigSvc.getToolbarConfig('editingDocument');
	let balloonToolbarConfig = await ToolbarConfigSvc.getToolbarConfig('balloonToolbar');
	
	// Build the editor
	return new Promise((resolve, reject) => {
		MultiRootEditor.create(
			this.roots,
			{
				plugins: [
					FontBackgroundColor,
					FontColor,
					FontFamily,
					FontSize,
					BalloonToolbar
				],
			   
				toolbar: toolbarConfig, // Config JSON blob pulled from EditorToolbarConfig.json
				balloonToolbar: balloonToolbarConfig,
				fontFamily: {
					supportAllValues: true,
				},
				fontSize: {
					options: [
						{ title: "8", model: "8pt" },
						{ title: "9", model: "9pt" },
						{ title: "10", model: "10pt" },
						{ title: "11", model: "11pt" },
						{ title: "12", model: "12pt" },
						{ title: "14", model: "14pt" },
						{ title: "16", model: "16pt" },
						{ title: "18", model: "18pt" },
						{ title: "20", model: "20pt" },
						"default",
					],
					supportAllValues: true,
				},
				fontColor: {
					colors: rgbColorPalette,
					colorPicker: true,
					columns: 3
				},
				fontBackgroundColor: {
					colors: rgbColorPalette,
					colorPicker: true,
					columns: 3
				}
			}
		)
		.then((editor) => {
                                document.querySelector("#toolbar").appendChild(editor.ui.view.toolbar.element);
                                this.editorInstance = markRaw(editor);
				resolve("Editor has been built");
		})
		.catch((error) => {
			app.config.globalProperties.messageModal.error('There was an issue with initializing the editor.');
			this._error(`There was an issue with initializing the editor`, error);
		});
	});
}

✔️ Expected result

The multi-root editor should be able to work in tandem with the balloon toolbar.
