dojox.dtl.dom.tag.test_tag_ifequal fails in FF

[liucougar]

fail in both FF3.6 and 3.0 (with trunk at r22726)

[liucougar]

one workaround is to add the following line

if(key=='value')this._parent.setAttribute(key, value);

after line dojo.attr(this._parent, key, value); in dojox/dtl/dom.js

+1 - the root cause is the whole mess created by dojo.attr not working strictly on attributes.
