the buildd people maintain their own branch of sbuild. It is likely fixed in
their branch.

In Debian the problem you found seems to have been fixed since commit fec82ed7
(which implemented an unrelated feature). So your problem should be fixed
starting with sbuild version 0.66.0.

Awesome that you found it!

Thanks!
