Leaving you off the explicit CC-list is surely unintentional. In fact, I didn't know about the original issue, I was just added by Sebastian to the ongoing conversation and so I believe I CC'd everyone who took part in it.

Thanks for addressing this!

(I'd appreciate Cc'ing me on this though since I was the one who reported it initially...)
I'm glad it helped. Leaving you off the explic= it CC-list is surely unintentional. In fact, I didn't know about the or= iginal issue, I was just added by Sebastian to the ongoing conversation and= so I believe I CC'd everyone who took part in it.
