[winswitch] DATA FROM ONE SOCKET IS REDIRECTED TO ANOTHER SOCKET

[dusan@dussan.org]

I don't know if this a bug or not.
My problem: I run two different instances of libreoffice (calculator and writer) on same machine but on the different displays and the different ports. If I connect with XPRA Html5 clients, the program (libreoffice writter) which I have to see on the second HTML client is showing on the first HTML client.
If I do the same with the another program, like a xterm, this never happend.

How to reproduce: run the bellow commands one the same server.
xpra start :11000 --bind-tcp=0.0.0.0:11000 --tcp-auth=none --mdns=yes --start="localc"
xpra start :12000 --bind-tcp=0.0.0.0:12000 --tcp-auth=none --mdns=yes --start="lowritter"

Then connect with one web browser to the port 11000 and with another to the port 12000 (to the server from where you run xpra commands). You will see that libreoffice witter from the port 12000 is showing in the web client which is connected to the port 11000.

I'm using latest XPRA software which is running on Debian 9.
