I noticed a counterintuitive behavior of Moby which is ignoring ADD --chown flag when it is used in conjunction with a compressed file. Moby project had several duplicate issues because of this. It would be better if Moby prohibits such use or displays a warning. What do you think?

I also could not find out where this behavior is documented in the official docs. If this behavior is not documented, it might be better to document it explicitly too.
