Problem description

I was looking over recent PRs, and I noticed that we used to have the fowarding added in #4876 but reverted it due to #4100, we really should add a test to verify we didn't break anything.

Reproducible example code

See #4100

Is this a regression? Put the last known working version here if it is.
