Thanks @sylvestre for the patch! Sorry I missed that this would be an issue in my review of #126193. Note: that got backported to release/20.x, so this will need to be backported as well. As such, I'll tag #126358 as a release blocker.  Sorry for the mess; or rather thank you for cleaning up my mess!
