The three tests that failed, also failed in master eg buid 1898 and I don't think they are related to my PR.

Hey @daniel-beck thanks for the approval, does this need another approval before merge?

[daniel-beck]

I do not maintain this. It only looks like I'm a maintainer with the green checkmark, but that's because I'm an org owner.

@bitwiseman Hey, is there anything else I need to do to enable this to be merged?
