Description
If wrapInner is called from within the body of a page, it runs itself twice, and any other scripts in the body run twice regardless of where wrapInner is run. Consider this code snippet to duplicate.
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.0/jquery.min.js"></script>
</head>
<body>
<div id="initialdiv">this is the main div at first</div>
<div id="anotherdiv">this is another div at first</div>
<script type="text/javascript">
$(document).ready(function() {
$('body').wrapInner('<div id="bodywrap"></div>');
});
alert("watch me duplicate");
</script>
</body>

The use case is for when you don't have control of a page's source code and need to modify it (in my case to wrap it in two divs with margin:auto on each, to center the page). The docs describe the method as a way to move elements around, but it appears to be recreating them. With traditional JS I would do this: http://jsfiddle.net/adGZS/. So it may just be a documentation issue if there is an alternative jQuery method to wrap items by just moving the children into the wrapper.

We're going to reopen this and try to fix it internally. Anyone who manually removes and then reinserts scripts is responsible for making sure they don't re-execute.

Duplicate of #10470.
In my opinion, this feels like a weird way to be using wrapInner... this seems like it's expected that it would re-run the script block if it has to restructure the DOM.
In any case, here is the jsfiddle: http://jsfiddle.net/jboesch26/5ynpG/
