I think this is a sporadic test failure as 4f255a4 only contains documentation changes

[cjmctague]

Thats what I assumed but was just documenting it

Thats what I assumed but was just documenting it

That's the correct thing to do. Anytime we see a failure unrelated to the PR, we should open an issue. However, I don't always do this. I think this is a duplicate of #585.
