When using .find(':hidden') , Chrome and Safari return <br /> elements in addition to elements that you would expect. Firefox and IE (9) do not find <br /> elements.

Test case:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "">
<html xmlns="" xml:lang="en" xmlns:tal="">
  <script type="text/javascript" src=""></script>
  <script type="text/javascript">
	$(document).ready(function() {
		var hidden_elements = $('#test').find(':hidden');
		var len = hidden_elements.length;
	<div id="test">
		<br />

Confirmed. I thought it might be due to <br /> elements having different heights in the browser but this shows they both return 0 for height:

Sticking this here for future reference:

This offsetHeight during the selection is 19, but the offsetHeight during the height() check is 0 because it goes through swap, which applies display: block before checking because offsetWidth was 0. So, the different codepaths make sense now, but this is a pain.

Possible solution would be to check width === 0 OR height === 0, but there may be a reason why do both.

Treat elements as hidden when either offsetWidth OR offsetHeight is 0. Fixes #13132, #10406.
