MS Forms tab in MS Teams - display issue with Likert Question

Morning, noticed quite a quirky issue which started two days ago.  We have quite a few forms embedded into Teams channels as a tab, using the Forms tab type.  Suddenly, all of them with a Likert question type started having a stylesheet issue.

If you look at the form in a browser, or if you embed it into Teams as a "Website" tab type, it loads just fine.

So I've got the workaround, just wanted to log the issue in case others are experiencing it.  Happy to hear any other thoughts though.
