When mod view was first released, raids did not pull a moderator out of mod view.

While the user could choose to leave the raid, it may be best if the default behaviour was to not leave the current channel when a raid occurs while the user has mod view up as a moderator for the channel.

By carrying the moderator away with the raid, they lose chat and history from closing mod view, as well as any actions they had not completed. As mod view does not retain much information asynchronously (this has improved a bit), being pulled out of mod view and losing the history of what happened in the channel during the stream is detrimental to a moderator.
