I think this should be read from a policy (app restriction), since we may want
to disable this, or (for enterprise usage) use something other than Chrome as
the source of this. Probably needs to be confirmed with the Unicorn team, since
we then have to make sure that the policy is set correctly for all WebView apps.

I was thinking maybe we could override it from policy to make the unicorn case
easier to support but what you said is definitely cleaner.
