> I've noticed that information exposed by the plugin is not reliable. It 
> happens often that I'm connected to the internet via WiFi, and the plugin 
> says that there's no connection.
> It's not easy to reproduce it on-demand, but I reproduced it many times 
> recently. It happens most often when in the morning, I open the Cordova app 
> that was running in background throughout the night.
> Then, when I connect to Chrome Dev Tools, I can do a repl session like this:
> {code}
> > navigator.connection.type
> "none"
> > window.fetch('http://www.example.org').then(function(res) 
> > {console.log(res.status)})
> Promise {[[PromiseStatus]]: "pending", [[PromiseValue]]: undefined}
> 200
> Fetch complete: GET "http://www.example.org/";.(anonymous function)
> > navigator.connection.type
> "none"
> {code}
> So, the plugin thinks I'm offline, yet any HTTP calls done within the app 
> without checking if I'm offline or online, are successful (either from the 
> app or devtools).
> When I disable WiFi and reenable it, after a few seconds the plugin updates 
> its state and then it tells that connection type is "wifi".
> There are several possibilities here:
> - either system (or device driver) gives us incorrect information, or
> - cordova plugin is caching data and/or not listening properly to all the 
> events and/or incorrectly processing it
> and most probably the issue manifests itself when the device is asleep for 
> many hours (but I'm not sure about this).
> Note that I also noticed another issue, that sometimes the Chrome network 
> stack thinks I'm offline (when I do an HTTP call, it fails immediately and I 
> see network errors in devtools console) - and then I restart the Cordova app, 
> and everything's fine, all HTTP calls are ok - but this is unrelated to this 
> ticket, and perhaps a bug in Chrome.
> This ticket seems to be most likely a bug in the plugin, because as I said 
> before, doing HTTP call succeeds despite the plugin telling me that I'm 
> offline.
