            Bug ID: 138727
           Summary: AX: [ATK] Crash getting the orientation of a
                    MenuListOption after the MenuList was removed from the
                    document
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)

                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2

AccessibilityMenuListOption::elementRect() returns the value of the grandparent MenuList. If we have an existing MenuListOption and the widget backing MenuList was just removed from the document, calling AccessibilityMenuListOption::elementRect() will crash the web process.
