Becoming invisible makes you part all your MUCs

Description
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 from the specified resource to all contacts who would receive unavailable presence if the client sent .”, 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.)
