Cookie time to live bug using js-cookie package.

[aungpyaekyaw]

1. create react app.
2. install js-cookie
3. To store cookie in browser use Cookie.set('key','value',{expires:10});
4. According to the package, the cookie should only expire in next 10 days, but it's can only live to
   7 days. It's working find if we set the expires day to less than 7. And this bug only exists in brave
   browser.I tried to reproduce the bug in chromium but it works fine in chromium. SoI think this is
   related to the Brave browser only.

Actual result:

cookie can only live 7 days if we set to live more than 7 days.

Expected result:

cookie should expire only in assigned day.
