            Bug ID: 205131
           Summary: Web Inspector: unexpected tail call frame shown for
                    getter when paused in Inspector^2
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Inspector

Screenshot of the issue

Steps to reproduce:

- Enable DebugUI in a desk build
- Open Inspector[2]
- In Inspector[2], set a breakpoint at TabBrowser.js:263 (_tabBarItemSelected)
- In Inspector[1], click on a tab

=> Hits a breakpoint with call stack including a tail-deleted frame for TabBarItem.disabled. See screenshot. This should not be shown in the call stack, as .disabled was called well before LegacyTabBar.selectedTabBarItem setter is called (the next call frame up from the wrong call frame).
