Hey, @JustinGoheen - Any updates on this?

[jxtngx]

@krshrimali I am working several other PRs for Lightning, and have this slated for next week

https://github.com/users/JustinGoheen/projects/16/views/3

[jxtngx]

@krshrimali can you please let me know if this submission looks good, or if anything needs to be be changed

[krshrimali]

Hi, @JustinGoheen - I apologize for the delay. The Flash CI is down with around 14 reasonable failures, and I've prioritized it for this week - trying to get it done as soon as possible. Once done, it will allow me to come back to the amazing work you and other contributors have done in these PRs - and help merge them once they look good.

Unfortunately, I believe I'll be able to get back to this either by the end of this week or by the start of the next week. ❤️ I hope that's fine with you. Thank you again for your work!

Edit: Also, in case there are any major changes, and if you are occupied, I'll be happy to update this PR to help land this PR. :))

[jxtngx]

sounds good to me. thank you for the quick update.

[krshrimali]

Hey, unfortunately the fork is deleted, so we'll be unable to fix the failures and merge it. Thank you for your interest though, we appreciate that. :)
