heightStyle "fill" option works incorrect if accordion container height set in %

In my case height is 100%

Test example with original markup and CSS

I have solve the problem by addiing event listener on window resize.

var a = $("#accordion_container");

a.accordion( { collapsible: true, heightStyle: "fill" } );

$(window).resize( function() {

var h = a.height();

a.find(".ui-accordion-header").each(function() {

var e = $(this);

if(e.css("display") != "none")

h -= e.outerHeight(true);

});

a.find(".ui-accordion-content").css("height", h);

});

$(window).resize();

Since it is technically possible, I would like it to be implemented in mainstreame.
