Do you think once the chrome tab is closed, tab in atom should be closed?

Suppose we are composing a mail or drafting text in stackoverflow and we have opened the corresponding tab in atom editor. During editing session, Atom syncs with the chrome browser.
After we are done with that chrome tab, suppose we close the tab, currently, corresponding atom tab is left open. Do you think it should get automatically closed?
Just want to hear your views on this scenario.
