Possible wrong selection context

[gravityFlower]

Hello,

i have the problem that on calling Cq() on an element, there seems to be a problem with the context.
I'm loading a html file and filter the elements. Then i call Each() on the filtered list of elements.
In the assigned function, i call Cq() on the element. I assume that the element is the context for the applied filter( like jQuery $("<filter-expression>",element). But the result contains all elements of the site matching this expression. You can see this in an example here:

I hope you can tell me if i'm doing something wrong or if this is a bug.
If this is intended, it would be best to document this feature.
