Ah gee - it looks like there isn't an active editor. Were you on a non-editor page, e.g. the config/packages page when this occurred? I think the package tries to ensure an active editor, but I might have missed a case

There's a high chance I was in a non-editor page but I remember being just in an untitled editor when I was testing with a friend. The text would duplicate from his to my editor like 5x. so 'Hello' would become 'HHHHHeeeeelllllooooo'

I'll try to recreate it again later if you want more info. Probably a freak edge case.
