Hi,
I report you an issue with any version of jQuery.
<body>
<div id="homepage">
<div id="homepage">
<div class="the-wrong-element-targetted"></div>
</div>
<div class="I-want-to-target-this-one"></div>
</div>
</body>
When I execute jQuery("body>div:eq(0)>div:eq(1)") I should find the element with the class "I-want-to-target-this-one" but the element return have the class "the-wrong-element-targetted"
You can see the bug with the last version of jQuery here:
