This is another instance of bug 1411008, we changed the message a while ago.

The TL;DR is that editor tries to get the style of NAC, and that NAC is detached from the document by the style flush that we need to do in order to get the up-to-date style.

We could wallpaper it I guess... But the answer we'd give would be nonsensical. We could also just make flushing styles really only flush styles, and that'd make the reframe of the NAC container not happen, and thus everything would make a bit more sense...
