not sure how prevalent this is but it definitely couldn't have been caused by the change where I saw it

This is supposed to be fixed in staging. I see that you found a hit in the base branch.

cc @liveans I think it was you who fixed this, correct?

Let's keep this open just so that we have an issue to track the remaining hits. If it all went well, the issues should go away once we flow staging to base.
