I had to use some odd Chrome command line arguments to keep a particular fragile kiosk-mode-like use of a prototype working long enough.

It worked for our purposes, but we feared an update might break it. I went to some effort to prevent updates outside our control.

(The command line arguments can be removed over time. Also, the behavior/correctness can change over time. I wouldn't expect all combinations of arguments to be tested in all future releases.)
