            Bug ID: 193103
           Summary: AX: VoiceOver does not read aria-live region text more
                    than once
           Product: WebKit
           Version: Safari 12
          Hardware: Macintosh
                OS: macOS 10.12
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Accessibility
          Assignee: webkit-unassigned at lists.webkit.org

(Originally filed this bug with Apple (#44301219), and got an email from them telling me to file it here instead, as it seems like a webkit issue. Thanks for looking!)

Summary: VoiceOver announces text in an aria-live region just fine. However, if the text is removed from the DOM, then added again, VoiceOver ignores it. This is causing issues for our screenreader users. JAWS (IE11) and NVDA (Firefox) screenreaders both announce the text when it is added again.

Steps to Reproduce:
Please test this CodePen with VoiceOver: https://codepen.io/personable/pen/OojmGG

Expected Results:
Every time the text is added to the aria-live region, VoiceOver should speak it.

Actual Results:
VoiceOver reads the text the first time, then ignores it.

Version/Build:
MacOS Sierra 10.12.6

Configuration:
MacBook Pro (Retina, 15-inch, Mid 2015)
