Description
I think I have found a bug in the .outerHeight() jquery function. I'm trying to the the height of the children of <body>, and it appears that <script> tags have a height > 0 (in this case I get 20, in chrome browser). This is not expected: in my opinion they should have a height = 0.
THIS IS MY CODE.
<html> <head>
<script type="text/javascript" src=" http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"> </script> <script type="text/javascript">
$(document).ready(function() {
var children = $(document.body).children();
for (i=0; i<children.length; i++) {
height = $(children[i]).outerHeight(true); console.log("height=" + height);
}
});
</script>
</head> <body>
<script type="text/javascript"> var a=1; var b=2; var c=3; </script>
<div>
<p>hello1</p> <p>hello2</p> <p>hello3</p>
</div>
</body> </html>

This happens because the width/height cssHook does a visibility swap when it encounters an element with no offsetWidth/offsetHeight. It reports a value because even style and script tags can get width/height when they are absolutely positioned and given display:block.
Two options:
- needsdoc that it reports weird values for style/script
- before visibilty swapping, detect nodeName "STYLE" or "SCRIPT", which begs the question of "what other elements should always report zero besides style and script?".
I'll open a PR just in case we want to go with option 2.

I'm inclined to say needsdocs. It seems pretty obvious that one shouldn't call width/height on style or script tags. And why loop through all of the elements on the page? I can't actually see where that would be useful.

Also is broken on input:hidden tags in chrome. I opened a PR just in case: https://github.com/jquery/jquery/pull/547
It's pretty small. Also, here's the perf... looks pretty good: http://jsperf.com/outerwidth-on-hidden-elements

Initial docs added to http://api.jquery.com/height/. I've pinged Dave and Karl about turning the notes into a reusable.
