This seems to only happen on Cosmic and later. + + [test case] + slightly unfortunately, the only way we've been able to reliably reproduce this is to get the CPC team to run their tests in azure, so we'll have to rely on them for SRU verification too + + [regression potential] + The change is fairly simple and was thoroughly reviewed and tested before it got uploaded to focal, and the backport is trivial so I am confident that the regression potential is slight.
