captureNetworkRequests not working in NW 2.6.3 after browser is re-opened

[shashank-dharap-checkr]

We are using captureNetworkRequests method to record API calls in chrome.
In a .js test suite file, we call the above method under beforeEach.
In first test , APIs are recorded successfully.
In afterEach, we call browser.end()

Issue - In second or later tests in same file, we noticed that NW does not record any API calls.
How can we close the browser and re-open it in each test but also network calls ?
Is there a specific capability or setting we need to enable to make it work ?
