This one is really a blocker for us as we have to put something into
production really soon with 4.4.2 and we can't do it atm. I take the
liberty to open a JIRA issue so that I can start working on a PR with
a test showing what we do and a fix.

While it looks like it was not an intented feature at the time, it's a
very useful one so it would be nice to make it work again. I don't
think it has any drawbacks to come back to the preexisting behavior.

I understand there probably won't be a release of 4.4.x soon (if any)
to fix this but, once we agree on the fix, I can deploy something on
our internal repo.
