I see nothing.   But it's weird that when I look at Network for the previous terminal
tabs only shows 4 (css files) - not even all the css files.

Not much. This is with -d 31:

end of output after opening window 2:
[2018/06/21 18:29:48:2084] DEBUG: 0250: 0A 0D 0A                                           ...
[2018/06/21 18:29:48:2084] DEBUG:
[2018/06/21 18:29:48:2086] NOTICE: client connected from localhost (, total: 2
[2018/06/21 18:29:48:3363] NOTICE: started process, pid: 8971

count to 10, then type C-S-N, which sends an OPEN-WINDOW (domterm command) to the server
(over window 2's websocket connection).  The server then runs a command like 'chrome --app=URL' or
'firefox URL' (depending on the initially selected browser front-end).  Then I see:

OPEN-WINDOW 'file:///home/bothner/.domterm/default.html#geometry=800x800' geom:800x800
[2018/06/21 18:29:55:7203] NOTICE: frontend command: /usr/bin/google-chrome --app='file:///home/bothner/.domterm/default.html#geometry=800x800&geometry=800x800'

and then nothing.

Both of these messages are from domterm, not the lws library.
