            Bug ID: 265683
           Summary: AX: add Mac API to get selected text range overlapping
                    static text element
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Accessibility

One of the things preventing VoiceOver from being able to use WebKit entirely off the main thread is that it wants to be able to access the range of a static text element that's part of the document selection, if any.

Doing that using text ranges is complex and hard for WebKit to optimize. A new API that provides this information directly can be computed efficiently using the isolated tree.
