Comment 11 for bug 1835968

Looking through the upstream repository for what landed after the aforementioned patches, there aren't further changes against buffering.rb. I'm not noticing any clear followup fixes to changes to patches in this patchset. So, it might be worth testing if this issue is also reproducible in the upstream ruby2.5 tree.

In eoan and disco, just spot checking individual files looks like the upstream changes are not present, so as Christian said in comment #6 this change appears to have landed in bionic without being applied to eoan or disco.
