Comment #31 on issue 933 by metaweta: jQuery expects "expando" attributes
http://code.google.com/p/google-caja/issues/detail?id=933
As part of the fix for this, unrecognized attributes on tags should be made
part of the attributes___ map we put on the node when using getAttribute
and setAttribute.
var atype = getAttributeType(tagName, attribName);
if (atype === void 0) {
// Unrecognized attribute; use virtual map
if (!this.node___.attributes___) { this.node___.attributes___ = {};
}
this.node___.attributes___[attribName] = String(value);
} else {
