Hi @opusforlife2,
I was able to reproduce the bug on my end, and I’d like to start working on it with a few colleagues. Could you please assign it to me?
Thanks

@Jugraj1 You can do so, but there's a very low probability of them being reviewed any time soon. If you're still okay with that, please go ahead!
