@chutzimir This is awesome. Thank you for taking the time to submit this patch.

Please could you add a spec test to demonstrate the case & then I will merge.

@chelnak I missed your message, but added the spec just now, also rebased on main.

@chutzimir Thanks! Looks like you have some rubocop errors to fix before we can merge.

Please could you take a look?

@chelnak I think I addressed all of them. Should I squash those commits or is it OK as it is?

[chelnak]

Yes- could be great if you could clean up those commits a bit.

Thanks!

Done. It is three commits now, with each of them meaningful and independent, bringing its own value.

Oh no the rubocop errors have reappeared!

Wack!

I now learned how to run rubocop locally before pushing. It was clean for me, let's see if the official pipeline agrees.
