document fragments leak script tags into the DOM

[gibson042]

jQuery.clean only scans for embedded script tags under element nodes, skipping documents and document fragments. As a result, script tags are erroneously added to the result fragment and ultimately to the DOM.

Actively looking for "new" bugs by creating contrived scenarios, instead of addressing real use cases blockers is counter productive at this stage in jQuery's growth.

I found it while trying to improve manipulation.js. If this were intentional, it would have hindered the effort. Since it seems to be don't-care, I offer this:  https://github.com/jquery/jquery/pull/680.

Yes, please see my comments on the PR and on the other ticket.

Upon re-reading jQuery documentation, document fragments are not supported inputs, meaning this ticket can be closed and the behavior in that case truly a "don't care". Again, my apologies.
