           Summary: Manipulating SVG element attributes in Javascript does
                    not work as expected
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
               URL: http://www.go2mk.com/temporary/Webkit_SVG_Bug/webkit-b
                    ug-demo.xhtml
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: SVG
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mohannad.hussain at agfa.com


Our application is almost pure Javascript, where we do tons of SVG work.
However, we find that manipulating attributes of SVG in Javascript either makes
no difference, or renders the image wrong (wrong size, wrong clipping...etc).

In the URL example,
http://www.go2mk.com/temporary/Webkit_SVG_Bug/webkit-bug-demo.xhtml, I am
removing the viewBox attribute and nothing happens on the screen. The work
around I discovered that works is to find the div containing the SVG and do
div.innerHTML = div.innerHTML!! Removing the node completely, replacing it with
another, then placing it back seems to work too.

We have seen this problem with many attributes other than viewBox, like the x,y
coordinates as an example. Functions like forceRedraw() seem to make no
difference. 

We can confirm this problem is happening on Windows and Mac. We have both
Chrome and Safari running webkit 532.5 and 531.21.8 respectively.

This could be related to issue #16491, but I am not 100% sure.

Thanks for your help!
