So, I see the same behavior with both 1.9 and 2.0. The behavior I see is that if the data is a complete HTML page (with doctype, etc.), then jQuery won't treat it as an element. That is, $(data).find("validSelector") will not find any elements. However, if I wrap the results in a <div></div> first, then it works.
Here's an example using jQuery 2.0:
And here's the same example using jQuery 1.9.1:
They both work, but if I remove the wrapping div, they both fail.
