            Bug ID: 178804
           Summary: Web Inspector: Canvas Tab: first WebGL canvas on
                    acko.net disappears, but still has path component
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
               URL: http://acko.net
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Inspector
          Assignee: webkit-unassigned at lists.webkit.org

                    webkit at devinrousso.com

Steps to reproduce:

1. Load Web Inspector on about:blank
2. Navigate to acko.net
3. Wait for the initial animation to finish
=> Canvas 1 disappears from overview, but still has a path component

This reproduced most times for me. It's really confusing. If the canvas got GC'd maybe we should not show it in the overview, but still list it in the navigation sidebar and gray it out? I think we try to do something similar (or have considered doing so) for resources that have been discarded or GC'd. Blob resources are a good example of this.
