setClass fails on SVG documents

[guest]

This is related to ticket #3878, and could be seen as an extension. But, different failure, different bug. dojo.html.setClass almost works on an SVG document node. It fails when it tries to assign the node className directly from a string after calling node.setAttribute ("class", classStr);

There is probably some platform where the assignment is necessary. I've attached a patch that leaves the assignment, but fixes the exception on SVG document nodes.

Yep, good catch on the version change.

I discovered the fix for this in 0.9 in dojox/gfx/_base.js, _hasClass, _addClass, etc... They've been suggested as improvements for inclusion in dojo mainline.

(In [10067]) Fix getClass/setClass to be SVG friendly (0.4 trunk), fixes #3929, fixes #3878.
