non <ul><li> tags doesn't work for custom tabTemplate

I've tried to create tabs with tabTemplate: "<div><a href="#{href}"><span>{label}</span></a></div>"

i.e. I've placed some divs into internal parent div, and find that here is an error while calling tabify method.

At lines 47 and 221 in ui.tabs.js here is a concrete li tag selectors:

l47: this.$lis = $('li:has(a[href])', this.element);

l221: var $li = $(this).parents('li:eq(0)'),...

I've changed that selectors:

'*:has(a[href])' and '*:eq(0)'

It's enables useing another tags, similar to my example.

I think this way is more flexible for users while it's allowed to use custom template : )
