It looks like the thread is still going on, and the "test case" is too large to show whatever problem is implied by the vague title "Selector and unexpected behavior".
There are a lot more people on the forum to help solve a problem like this, when you have a lot of code and it's not clear the problem is a bug in jQuery. This area is for reporting bugs in jQuery.
Just leave this ticket closed, and open a new one *when you have a clear description and test case that demonstrates a bug.*
Here is an example: http://dev.jquery.com/ticket/6869
