            Bug ID: 236291
           Summary: AX: SVG with role=tree: aria-label dropped on iOS
           Product: WebKit
           Version: Safari 15
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Accessibility
          Assignee: webkit-unassigned at lists.webkit.org

Minimal test case: https://codepen.io/pkra/pen/abVpaBr

On VoiceOver (iOS 15.3), using read-all (two-finger swipe up) or by item (swipe right/left), VO voices "image" (i.e., wrong role and missing accessible name). 

It seems like Safari is not exposing the SVG's role and name correctly.

For comparison, the test case includes wrapping the SVG in a span and using the span as a tree root; this gives the same result in read-all ("image") but by item VO voices "circular tree, image, tree start" (which is a different kind of weird but looks more like a VO issue).

On MacOS Safari 15.3 the SVG is treated as a tree and its name is read correctly by VO. (Similarly on other OSs / ATs)
