[Bug 23565] cloneNode IDL does not match reality

https://www.w3.org/Bugs/Public/show_bug.cgi?id=23565

--- Comment #15 from Boris Zbarsky <bzbarsky@mit.edu> ---
That is, I think there is a good chance of Gecko making this change breaking
content, due to content-sniffing and Gecko-only codepaths.  :(

We would _definitely_ break a number of Firefox extensions; I just checked and
a bunch of them use cloneNode() with no arguments and expect deep clones.

We might be willing to go through all that breakage if there were a very strong
reason to, but in this case, I just don't think the reasons are strong enough.
