Looks like this was already fixed in master, as part of some other changes: https://github.com/dovecot/core/commit/b200bc3875fa06d42c8619865cc306c3297fcacc <https://github.com/dovecot/core/commit/b200bc3875fa06d42c8619865cc306c3297fcacc>

We're planning to get v2.3 releases out in not-many-more-months, so may have to wait for it.
