[bug] open doesn't close the app and the socket on mac and linux #287

Issue description :

• The open dependency doesn't close the socket even after the app has closed on Mac and Linux

Reproduce steps -

Scenario 1

open("https://google.com", { wait: true }).then(() => console.log('closed'))

The above doesn't close the socket and doesn't print "closed" on Mac and Linux OS. Works as expected on windows

Scenario 2

When we use the newInstance argument, it opens on a new browser tab on MacOS but closes the socket as expected. However, no such workaround is available for linux OS.

open("https://google.com", { newInstance: true, wait: true }).then(() => console.log('closed'))
