RTL (right-to-left) comment text in Word 365

I'm running Mac OS 14.0. In both Word 365 on a Mac (Microsoft Office 365 for Mac version 16.80) and the web version, I can't get RTL (right-to-left) text to appear in comments. This type of text is used in Hebrew and Arabic, for example. In both cases, there's no problem with RTL text in the body of the document. But when it comes to the little comment bubbles that appear on the right side of a Word document, the formatting options are limited. For example, on Word for Mac if you highlight the text within a comment and right-click it, there aren't any formatting options. The web version, by contrast, does show formatting options when you right click, but they don't work for me. I can select Text Direction > Right-to-Left, but then nothing happens to the text in the comment bubble. This is a real problem for collaborating with others using Word for Windows, where apparently this is not a problem.
