How about this?
$.fn.owns = function(selector) {
var owns = [];
this.filter('[aria-owns]').each(function(){
owns.push('#'+this.getAttribute('aria-owns').replace(/\s+/g,',#'));
});
return this.find('*').add(owns.join()).filter(selector);
};
Real children get precedence over the aria-owns stepchildren with this
approach. It seems to work for your situation but I don't know if
that's the right interpretation. Also, the selector is limited to the
"simple selector" used by filter(), basically that means no descendant
or child selectors can be in it.
