Inconsistent behavior with .replaceWith() and disconnected nodes.

[https://github.com/ironchefpython]

I noticed odd behavior using replaceWith on disconnected nodes. I use a lot of html fragments, and I was getting strange results depending on the presence or absence of text.

Here is the minimal test case:

> jQuery("<span></span>").replaceWith("<div></div>");
[<div>​</div>​]

>jQuery("<span>foo</span>").replaceWith("<div>bar</div>");
[<span>​foo​</span>​]

This bug may be a duplicate of http://bugs.jquery.com/ticket/7246, however that was closed 15 months ago with no indication of if the non-deterministic behavior is intended.

Fixes #11338, .replaceWith should work on detached nodes.

This seems like a pretty major regression seeing that this behavior was supposed to be supported in 1.4. Why is this being pushed back to the 1.8 release instead of being released as a patch?
