Formula bar autocomplete within Fluent UI Panel

[MarkMpn]

I'm not sure if this should be directed to the Fluent UI or Monaco teams instead, please advise if so.

I'm trying to host the formula bar within a Fluent UI <Panel> control. The formula bar appears as expected, but the autocomplete list does not appear. To repro, edit the PowerFxDemoPage.tsx component, add the import:

import { Panel } from '@fluentui/react/lib/Panel';

and wrap the entire contents of the component in a <Panel>:

<div>
  <Panel isOpen={true}>
    <h3>Context</h3>
    ...
    <FetchData />
  </Panel>
</div>
