           Summary: Becoming invisible makes you part all your MUCs

Joining and leaving MUCs is based on your presence. So I shouldn't have been
surprised that becoming invisible made me leave all the MUCs I was in; but I
was. I imagine a normal person would be even more surprised.

We could try to be smarter about the privacy list we use, adding action='allow'
rules for presence-out for the MUCs we're in, modifying it when we join/leave
MUCs. (XEP-0126 makes no mention of MUCs whatsoever.)

In XEP-0186, it's slightly up to the server… The XEP says that “When the client
enters invisible mode in the midst of a presence session (i.e., after having
previously sent undirected presence with no 'type' attribute), the server MUST
send <presence type='unavailable'/> presence from the specified resource to all
contacts who would receive unavailable presence if the client sent <presence
type='unavailable'/>.”, which presumably includes MUCs. But it also says that,
while invisible, the server “MUST deliver directed presence stanzas generated
by the client.” which allows the user to *join* MUCs while invisible. (Again,
no explicit mention of MUCs is made.)
