Hello @swendlandt ,

Thank you for reporting the issue. I am the accessibility expert of the team owning the InvisibleMessaging service. I did some analysis of the issue and I the results are that the issue is a VoiceOver related one, not a ui5 web component specific problem.

The issue is not reproducible with JAWS 2024 + Chrome latest and NVDA + Chrome latest, so this is rather a lack of screen reader support for Voice Over + Chrome and has nothing to do with an issue with the coding of the UI5 web components.

As suggested here our recommended testing environment is Chrome + JAWS 2024 as it shows the best support of ARIA and WCAG standards. Please read more about testing components for accessibility here: https://sap.github.io/ui5-webcomponents/nightly/docs/advanced/accessibility/

I would suggest that you could raise an issue to VoiceOver. As there is no bug in the web components project I am closing the issue.

Kind Regards, Elena
