I used to think it only counted people in the group who have OQ installed, so for example, if the tanks don't have it, they won't show up in the list. But obviously the mods would be able to answer this with an actual answer. :-p
I don't run anything else that auto accepts invites though, and I've been mass-booted when raids disbanded. The RL has re-invited everyone, but it wasn't due to elvui or anything. (I don't use it.) So it could be due to that some of the time, but I still suspect something else is amiss. (No idea what, though. sorry. lol)

I've had entire raid groups get disbanded before. Pretty sure ti's a bug but i don't know how to reproduce it. It seems entirely random. :(
