window.navigator.onLine always returns false

[piperone]

Description

Sometimes, particularly in a PWA context, it is necessary to check if the user has an active internet connection. This is easily achieved in other browsers by simply checking the value of window.navigator.onLine. In Brave, this value is always false.

This could very well be intentional, but I don't see how removing this enhances user security or anything like that.

Steps to Reproduce

1. Open the console on any page
2. Type "window.navigator.onLine" or "navigator.onLine"
3. The value returned should is false

Actual result:

The value false is returned

Expected result:

The value true should be returned when the user has an internet connection
