I realize that, but do you all think that this is the expected
behavior?
I would not expect the implementation to *select* elements outside of
the context scope, but I would definitely expect it to consider such
elements for the *selector evaluation*. In my mind, the selector
evaluation is absolute and independent of the context node, only
considering the structural relationships.
In this case, the first span
1.) *has* a parent div.div_a after all, and that is what the selector
says (and this part has nothing to do with the context element), and
2.) it *is* a descendant of the select() context element
so I think it should be selected.
The implementation as it is now mixes up these two things, in a way
that is really suprising for me. I'm not saying it's wrong, but if
this is intended, I think the documentation should mention that the
context node does influence the selector evaluation.

I just read what Resig wrote and this is interesting:

To me this is *exactly* the way I would have expected it to work. I
guess what's intuitive for one person is surprising for the next :-)
