I'll take a stab at this. If possible, please assign it my way.

Can't assign if you are not part of the team but I can create a tag for you ;)

@tonyskapunk I think github did not close this issue because a second PR references this issue as well and that PR is still open. Just a heads up.

[tonyskapunk]

That's correct. This should be closed once the new PR is merged, thanks!

Closing this one now! Thanks for the help @Komish
