From the code, it seems this is a dictionary?

[Daniel Nishi, 2014/08/15 16:56:45]

chrome/browser/ui/webui/options/website_settings_handler.cc:318 declares the
passed value as a ListValue, so I assumed that was an Array for typechecking
purposes.

[Bernhard Bauer, 2014/08/15 17:13:04]

Oh, I overlooked it's the whole arguments array.

CallJavascriptFunction() actually has a version that takes more than one
argument, so you can directly pass the correct arguments without having to
unpack them. (And then permissions can be declared as a dictionary.)

[Daniel Nishi, 2014/08/15 17:33:46]

Done.
