            Bug ID: 179943
           Summary: AX: Updated aria-label not read by VoiceOver
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: iPhone / iPad
                OS: iOS 11
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Accessibility
          Assignee: webkit-unassigned at lists.webkit.org

When the aria-label of an item is updated, VoiceOver continues to read the ‘old’ value. An example of this is in the following fiddle:
https://jsfiddle.net/7rwpd0wL/3/
Click the ‘Push me’ button and you’ll see that both the text and aria-label of the div have been updated. However, iOS VoiceOver will continue to read “aria label one”, not “aria label two”.

The real-world scenario I am seeing this as an issue in involves updating a re-used header as different portions of the page are changed. There are ways to make it work, but involve restructuring the page to not re-use elements. Re-using should is valid html/js and should be permitted.
