Some dialog titles are not announced
When opening the dialog in this codepen, ORCA does not announce that a dialog opened, skips the dialog title and subtitle, and only announces the "close" button. As far as I can tell, the dialog is coded correctly (with role=dialog and labeled with aria-labelledby), and is announced as expected by JAWS and NVDA on Windows. Strangely, other modal dialogs are announced correctly by ORCA, so it seems to be specific to the combination of ORCA + the fluentUI dialog component.
Environment: Ubuntu 20.04.4 LTS, ORCA 3.36.2, Firefox 101.0.1
