It will go overtime

[Mamuko500]

I would want it to stop automatically and from time to time, it does, but there are times when it just goes overtime. For example I set it for five minutes and once those end, it just goes overtime and doesn't stop unless I stop it. I want it to stop automatically once those five minutes are up. Any fix for this?

What do you mean? the timer goes into negative digits? have to tried different browser? I do not have this behavior and not sure how to reproduce, feel free to let me know
