DOM traversal predictably breaks when $ instantiated with a string of HTML

Description

When passing the jQuery object a HTML string, DOM traversal works unexpectedly.

// the result for these is "undefined."  if the first two were standalone documents that loaded in
// jquery, the result would not be "undefined."
console.log($('<html><body><div id="test">test</div></body></html>').find('body').html());
console.log($('<html><body><div id="test">test</div></body></html>').find('#test').html());
console.log($('<div id="test">test</div>').find('#test').html());

// the result to these is correct.  the only addition was adding a plain wrapper div.
console.log($('<html><body><div><div id="test">test</div></div></body></html>').find('#test').html());
console.log($('<div><div id="test">test</div></div>').find('#test').html());

i don't understand how this is not a bug. is it a feature to work incorrectly? thanks for the helpful comments on why exactly this is not a bug, when it works the opposite of logic. go ahead, test it out http://jsfiddle.net/8zvWX/

"When passing in complex HTML, some browsers may not generate a DOM that exactly replicates the HTML source provided. As mentioned, we use the browser's .innerHTML property to parse the passed HTML and insert it into the current document. During this process, some browsers filter out certain elements such as <html>, <title>, or <head> elements. As a result, the elements inserted may not be representative of the original string passed."
