Thanks for your work on this! Overall I think this looks good, but some ideally we'd like to destructure the props that are being passed to this component. Due to several other PRs we have for this issue, I'm going to close this one for now. I'm sorry we couldn't get this in, but please feel free to check out our other issues!
