Yes, I did get it closed. I did some manual pulling on the slide from the inside. I was extremely worried about all the cables, so I was trying to be as careful as possible.
So I jogged it in and out with the switches plus yanked on it. It did break loose and stow.
I could see that it was trying to move so I suspect a CB is unlikely. I was talking to the owners today and they said it did the same thing only once before, and they manually pushed it from outside and it pulled in, while on the inside the switch was activated.
