Is your feature request related to a problem?
Windows Narrator doesn't support role="application". NVDA is buggy on it too.
So, navigating between messages using up/down arrow keys are frustrating to PWD as they need to turn off scan mode.
Describe the suggestion or request in detail
Add <h5>/<h6> header to message. So PWD use H key to navigate between messages. This would not need to turn off scan mode.
Describe alternatives you have considered
role="application", but it is not supported by Windows Narrator, and buggy in NVDA.
