           Summary: Javascript created SVG disappears after div is hidden
                    and restored
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
               URL: http://195.137.123.15/chrome/test1.html
        OS/Version: Windows XP
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: SVG
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: steve.horsley at gmail.com


An SVG graph is drawn in the DOM by javascript. If the div is hidden and then restored(by setting Display to "none" and back to "block"), all the dynamic DOM elements have disappeared. Also, after hidihg and re-showing the graph, the non-dynamic SVG <g> element can no longer have dynamically generated children added to it.

The URL http://195.137.123.15/chrome/test1.html gives a small demo of the problem. I can hide the graph by setting the div visibility to "hidden" and the graph is still there after setting it visible again, but in this case it still occupies screen space which I don't want. So
