Could this PR be merged even with codecov complaining?

I made an one line change which has a test already.

Hey @omissis

First of all, thanks for helping maintain this amazing package. It's helping a lot the Go community.

Don't wanna rush you guys, I know that you are probably all busy. But, do you guys know when this PR is gonna get merged? (Can I help with anything else?)

[omissis]

hey, I have been sick the past week. I will check this out as soon as I will be up and running again. My estimate would be a week or two. thanks for your patience!
